Bed & mattress questions, answered

Pick mattress size from how many people sleep there, how tall they are, and how much floor space you have. A UK Single is 90 × 190 cm for one person. Couples usually need at least a Double (135 × 190 cm). King (150 × 200 cm) or Super King (180 × 200 cm) gives more width. Leave about 10–15 cm of mattress length beyond the tallest person’s height.

A standard UK Double mattress is typically 135 cm wide by 190 cm long (about 4 ft 6 in × 6 ft 3 in). It is not the same as a common EU/IKEA Double at 140 × 200 cm.

A UK King mattress is typically 150 cm wide by 200 cm long (about 59.1 × 78.7 inches). It is longer than a UK Double (190 cm) and narrower than many EU King sizes near 160 × 200 cm.

A UK King fitted sheet for a 150 × 200 cm mattress. Also match pocket depth to mattress thickness — often about 25–30 cm deep or 35–40 cm extra deep if you have a pillow-top or topper.

No. A UK Double is commonly 135 × 190 cm, while many EU and IKEA doubles are 140 × 200 cm — both wider and longer. Size names collide; centimetres decide fit.

Close but not the same. A US Queen is about 152 × 203 cm; a UK King is typically 150 × 200 cm. The US Queen is longer. Sheets and frames are not reliably interchangeable — compare centimetres before cross-border pairing.

A UK Super King mattress is typically 180 cm wide by 200 cm long (about 6 ft × 6 ft 6 in). That is roughly two UK Singles side by side in width, with King-length depth.

Both are usually 200 cm long. UK King is 150 cm wide; Super King is 180 cm wide — 30 cm more width for couples. Room space and doorway access often decide which footprint fits.

Children move from cot sizes to small singles and then often a UK Single at 90 × 190 cm. Always measure centimetres. Bunks and high sleepers have age and guardrail rules. This is size literacy — follow product safety guidance for your child.

A standard UK Single mattress is typically 90 cm wide by 190 cm long (3 ft × 6 ft 3 in). A Small Single is usually 75 × 190 cm for children or very compact rooms.

Many UK cot bed mattresses are approximately 70 × 140 cm. The critical rule is a snug fit in the specific cot so gaps cannot trap a child — follow the cot manufacturer’s stated mattress size rather than a generic label alone.

A UK Small Double (sometimes labelled queen in UK retail) is typically 120 × 190 cm. It is wider than a Single but narrower than a standard Double at 135 cm — useful for solo sleepers wanting stretch room in compact bedrooms.

Measure finished mattress thickness from base to highest top surface. Standard deep fitted sheets often cover about 25–30 cm; extra-deep sheets target roughly 35–40 cm. Pillow-tops and toppers add to the total depth you must fit.

Emperor is a non-standard UK retail size most often quoted as 200 × 200 cm — wider than Super King (180 × 200 cm). It is a marketing size, not a regulated British Standard designation.

Generally no. Folding or sharp bending can damage springs and comfort layers and may void warranties. Measure doorways, stairs and corners instead. Only roll or compress constructions when the manufacturer explicitly designs and permits it.

Pick a build type first (pocket, hybrid, foam, latex or open coil), then match spring tension or foam support to body mass, then tune surface feel to sleep position. Confirm UK size in centimetres and check the base meets the mattress warranty. Soft/medium/firm labels are not standardised.

Lock UK size in centimetres, confirm base and doorway access, then choose build type and support for your body weight before soft/medium/firm labels. Read trial and warranty small print and plan old-mattress disposal before delivery day.

Neither is always better. Pocket sprung uses in fabric pockets coils for responsive support and airflow paths; memory foam contours slowly with heat-sensitive memory foam. Choose by mechanism — bounce and ventilation versus deep moulding to shape — or consider a hybrid that combines both.

Spring tension is how hard the support unit resists compression and should suit body weight. Comfort firmness is the softness of layers above the springs. A mattress can have firm springs and a soft surface. Confusing the two is a common reason new beds feel wrong.

In UK retail, orthopaedic usually means a firmer or more supportive mattress marketed for alignment — not a regulated medical device. Check the underlying pocket, foam or hybrid construction and tension. Persistent pain needs clinical advice, not a label.

Side sleepers usually need enough surface give at the shoulder and hip so the spine stays nearer a straight line. Soft to medium pocket, hybrid or foam comfort layers often help; heavier side sleepers may need medium rather than very soft so hips do not drop. Firmness labels mean different things in different shops.

Ask what the support system is, which spring tension or foam density suits your weight, what base the warranty needs, and the written trial and body-impression rules. Soft, medium and firm alone are not enough.

Foam density is mass per cubic metre (kg/m³), not firmness. Higher density usually means more polymer in the same volume and often better resistance to permanent impressions. Soft high-density foam and firm low-density foam both exist — read density with ILD hardness and thickness.

Firmness is personal and also depends on body mass and sleep position. Soft surfaces allow more shoulder/hip sink for many side sleepers; firmer surfaces limit sink for many back and stomach sleepers. Soft, medium and firm labels are mean different things in different shops — compare feel on the same construction type.

Most mattresses have a cover, comfort layers and a support core. The core may be pocket springs, open coils, foam or latex. Edge foam and fire barriers can sit around the stack. Reading the layers helps you understand shop labels.

A bed-in-a-box mattress is compressed and shipped in a carton, then expands after you open it. Most are foam or hybrid builds. Compression is a delivery method. You still choose type, feel, UK size and a suitable base like any other mattress.

Higher prices often buy more fill mass, denser foams, finer pocket units, better edges or turnability — not a guaranteed better night for every sleeper. A cheaper bed with the right support can outperform a plush premium model that is too soft for you.

A pocket sprung mattress uses individual steel coils, each sewn into its own fabric pocket, so neighbouring springs can compress more independently than in an open-coil Bonnell grid.

Miracoil is Silentnight’s brand name for interconnected spring systems in the open-coil and continuous-coil family. Springs share load through a linked unit rather than sitting in individual fabric pockets like pocket sprung mattresses.

A single spring tension is always a compromise when body masses differ sharply. Zip-and-link systems pair two mattresses with different tensions in one Super King-class footprint. Pocket sprung and foam also differ in less movement felt from a partner for light sleepers.

Bed-in-a-box is mainly a delivery format: the mattress is compressed and rolled, then expands at home. Traditional mattresses usually arrive flat. After expansion, judge type, support, size and base the same way.

Memory foam is viscoelastic polyurethane foam that slowly recovers after compression and softens with heat. Density (kg/m³) and foam firmness rating describe grade better than thickness alone.

No. Spring count mainly reflects packing density in a stated size. Firmness, durability and comfort still depend on wire gauge, zoning and comfort layers. Always compare count within the same size and build type, preferably as springs per square metre.

A zoned mattress varies firmness by body region — often softer under the shoulders and firmer under the hips and lumbar area. Zones use different spring gauges, coil geometries or foam hardness bands. More zones are not automatically better if the firmness map does not match your body.

A hybrid mattress combines a spring core — usually pocket springs — with substantial foam or latex comfort layers above. Springs handle support and airflow paths; foam or latex handles surface cushioning at pressure points. The hybrid label means the comfort stack is a first-class design feature.

less movement felt from a partner is how little one sleeper’s movement disturbs the other. Foam and latex damp bounce; pocket springs isolate better than linked open coils. It is different from roll-together, which is drifting into a shared centre dip.

They can narrow type and firmness bands from sleep position and weight, but they rarely know your base, partner weight gap or a brand’s exact meaning of medium. Treat results as a shortlist, then check construction and warranty facts.

Reflex foam is a UK retail name for firm, bouncey high-resilience foam often used in sofa beds and guest mattresses. It is not the same as slow memory foam. Density and thickness still decide comfort and lifespan.

Pocket springs sit in separate fabric pockets; open-coil Bonnell springs are laced into one interconnected wire grid. Pocket units usually contour more independently; open coils share load across the lattice and typically transfer more motion.

A pillow-top has a raised comfort pad sewn above the main border seam. A tight-top quilts comfort layers into the main panel without that raised pad. Euro-tops integrate a pad flush with the edge. Pillow-tops are usually rotate-only, not flipable.

Memory foam is slow-recovering memory foam; latex typically rebounds faster and feels more buoyant. Memory foam contours deeply; latex often sleeps cooler relative to classic memory foam and commonly shows longer durability bands.

Fit the feet, stand the half bases together, join them with linking bolts until the top is flat, add drawers, attach the headboard, then put the mattress on last. Assemble large sizes in the bedroom so the joined base still fits through the door.

Decide storage need, then mattress compatibility, then room footprint. Platform-top divans and solid foundations suit most foams and hybrids. Slats need gaps within warranty limits. Ottomans need clearance and strut ratings. Adjustable bases need flex-rated mattresses.

Choose by fabric family first — plush velvet, crushed velvet, chenille, linen-look or faux leather — then by colourway. Fabric changes texture, sheen and care; it does not change mattress support. Pale colours show marks more; dark piles show lint. Order swatches under your room light when colour accuracy matters.

Strutted headboards bolt into sockets on the divan or frame. Floor-standing boards sit against the wall and are held by the mattress stack. Match the board width to the bed size and use spacer blocks if the mattress is very deep.

Join the base like a divan, fit the hinged lid, then install gas struts while supporting the lid. Use struts rated for your mattress weight. Keep hands clear of the lid path and check the headboard does not block the lift.

Divans are box bases that often use drawers for storage. Ottomans use a hinged, gas-strut-lifted platform to open a large storage void. Divans favour frequent small access; ottomans maximise volume but need clearance and correct strut rating.

A divan is a box-like upholstered base that supports a mattress. Tops may be solid platform or sprung-edge, and many include drawers. The mattress sits on the box rather than on an open bedstead with visible legs and slats alone.

A gas strut is a sealed tube of compressed gas with a piston rod that extends to help lift and hold the mattress platform. Newton rating must match platform and mattress mass at the hinge. Undersized struts make lifting hard; oversized struts can slam open.

Yes, if slat gaps meet the mattress warranty — often a maximum clear gap around 7 cm — so foam cannot hammock between laths. Solid platforms and closely spaced slats are usually safer for thick foam and hybrid comfort layers.

Match the base to your mattress warranty, storage need and room access. Confirm UK size in centimetres, slat gaps or platform rules, ottoman lid clearance and strut ratings, and doorway access for the largest panels.

End-lift ottomans hinge at the head and need clear space at the foot. Side-lift ottomans hinge along a long edge and need clear flank space. Both use gas struts; the difference is room planning and access, not storage quality by itself.

Choose by how often guests stay, which opening mechanism fits your floor space, and how thick a mattress the frame allows. Sit on it as a sofa and test the open bed footprint before you decide.

A true box spring contains coils in a timber frame and adds bounce under the mattress. A solid foundation is a rigid platform without coils. Many modern foam and hybrid mattresses need a firm foundation rather than a flexing traditional box spring — check the mattress warranty.

A four-drawer divan is a box base with four pull-out storage drawers, usually two on each long side. You need clearance for drawer travel on the opening faces. It is not the same as an ottoman, which lifts the whole mattress platform for one large void.

A platform-top divan has a firm, non-sprung upper surface. A sprung-edge divan embeds springs in the base top or perimeter, adding edge give under the mattress.

Put both mattresses on a flat joined base with the zip edges touching, align the head ends, close the zip fully, then add a bridge cover if you want less centre feel. Do not force the zip over fabric folds.

Ottoman beds lift the mattress platform on hinges assisted by gas struts rated for the combined platform and mattress mass, exposing a storage void in the base.

A Chesterfield-style bed or headboard uses deep buttoning or crystal tufting on padded upholstery, often with scrolled or winged ends. It is a furniture face style, not a mattress type. You still choose pocket sprung, foam or hybrid separately.

zero-gravity settings raise the legs and torso so body weight is more evenly distributed along the mattress, often reducing pressure at hips and shoulders. It is a comfort geometry label on adjustable bases, not a guarantee of medical outcome unless clinically specified.

A TV bed or media bed hides a screen in the footboard and lifts it with a powered mechanism. The mattress is still a normal sleep surface. You need power, clear foot space and safe cables.

An adjustable bed moves the mattress platform at the head and often the foot using motors or ratchets, changing torso and leg angles. Dual systems can split a wide bed so each sleeper sets a different position. The mattress must be flexible enough to bend with the platform.

Many foam and hybrid warranties require maximum clear gaps of about 7 cm between slats so the mattress cannot hammock into the voids and form permanent impressions.

Strutted headboards bolt into sockets on a divan or compatible bedstead and move with the bed. Floor-standing headboards stand on legs or sit trapped between wall and mattress stack. Wall-mounted boards fix to the wall independently — useful with ottomans and adjustable bases.

Sofa bed mattresses must fit inside a folded seating cavity, so depth is limited by the mechanism. Guest comfort is a compromise between daytime furniture volume and night support. Open footprints are often near Single or Small Double — confirm centimetres for the specific frame.

Birch and other hardwood or laminated sprung slats are often denser and resist set better than soft pine on long spans, but section thickness, gap, centre rails and span length dominate support. Material alone does not guarantee warranty-safe spacing for foam mattresses.

Many UK households use about 13.5 TOG or higher for cold bedrooms, while 10.5 TOG is a common mid option and 4.5 TOG suits warmer rooms. Room temperature and personal preference matter more than one fixed winter number. TOG measures insulation, not fill quality.

Side sleepers usually need higher loft to fill the gap between shoulder and head so the neck stays nearer level with the spine. Exact height depends on shoulder width and how soft the mattress is. Memory foam, latex, down and fibre fills differ in rebound and moulding to shape.

Percale is a plain crisp weave; sateen uses float yarns for a smoother, more lustrous surface. Both names describe structure, not fibre quality. Percale often feels airier; sateen can feel silkier and slightly warmer. Thread count alone does not decide which is better.

Not reliably. Thread count can be inflated by multi-ply yarn counting. Fibre quality and weave — such as percale versus sateen — usually matter more than the highest printed number. Long-staple cotton, linen, bamboo-derived fabrics and silk each bring different feel and care rules.

Weighted blankets distribute added mass across the body using glass beads or plastic pellets in baffled chambers. Even distribution matters more than filler name. gentle pressing feeling is the sensory idea — a comfort mechanism for some users, not a medical treatment claim. Users must be able to remove the blanket freely.

A protector is a thin barrier that shields the mattress from fluids and allergens while aiming to change feel little. A topper is a thicker comfort pad that softens or firms the surface. Use a protector under a topper if you want both hygiene and a feel change.

Cool the room and bedding first: airflow, lower duvet TOG, breathable sheets. Then look at mattress heat behaviour. Cooling pads are optional extras. Gel prints on foam are not air conditioning. Work as a system, not one slogan.

Active cooling pads circulate temperature-controlled water through channels in a thin pad on the mattress. Heat moves from the sleeper into the fluid loop and is rejected at a bedside control unit. Passive gel pads absorb limited heat without a pump.

Lifespan depends on core material: many foams last about 6–8 years, pocket sprung and hybrids often 7–10, and latex cores commonly 8–12 under normal use. Sag, broken support, or persistent discomfort with an aged mattress are replacement signals.

Consider replacement when support is lost — visible sag, springs felt through the surface, edges collapsing, or sleep pain that improves away from home — especially if the mattress is past typical material lifespan bands (often 6–10 years).

Remove soft toppers first. A solid platform or board over a flexing base can firm the sleep system. You cannot permanently firm a support unit that is too soft for your body mass with sheets alone — that needs a higher-tension mattress.

Add a soft foam, latex or fibre topper, or a thicker quilted protector, to change the first centimetres of contact. Toppers cannot fix a collapsed core or the wrong spring tension for your weight.

A mattress warranty usually covers manufacturing faults and abnormal sag beyond a stated depth. It does not usually cover soft or firm preference. Trials cover changing your mind about feel. Wrong bases, stains and missing protectors often void cover. Read your written warranty.

Many compressed mattresses are usable after about 24–72 hours if flat and visibly expanded, with full loft continuing over several days. Follow the manufacturer’s window. Do not sleep on a mattress still tightly compressed. Ventilate for initial odour.

Use council bulky waste collections, household waste recycling centres that accept mattresses, or specialist recycling where available. Reuse or charity routes only suit clean, structurally sound mattresses. Rules vary by local authority — check your council before disposal. Do not fly-tip or burn mattresses.

No. A body impression is a shallow surface dip in quilting or comfort foam. Sag is deeper support loss where the sleep surface hammocks. Light impressions can be normal; progressive centre collapse or springs felt through the surface are replacement signals.

Many foam and hybrid warranties prefer a solid foundation, platform-top divan or closely spaced slats rather than a flexing traditional coil box spring. “Box spring required” on older labels sometimes means an approved foundation — check whether coils are present and read the current warranty.

Rotate means spinning 180° so head and foot swap with the same face up. Turn means flipping upside down. Many modern single-sided mattresses are rotate-only; double-sided mattresses may use both.

Many mattresses settle over about two to eight weeks of regular use as comfort layers and quilting compress slightly. Mild early softening can be normal. Progressive deep sag or springs felt through the surface is not break-in — it is a support problem.

Higher loads need stronger support cores and sturdy bases so the surface does not hammock. Look at spring tension or foam density, not only soft/medium/firm labels. This is furniture advice only — not medical advice.

Classic memory foam has slower air exchange through its cell structure and softens with heat, which can increase warmth at the contact zone. Open-cell foams, gel modifications, thinner comfort layers over pocket springs, and lower-TOG bedding each change heat pathways differently.

Vacuum the surface, spot-clean spills with a barely damp cloth, and dry fully. Do not soak foam cores. Care differs a little by pocket sprung, foam and latex — follow the maker’s label.

OEKO-TEX STANDARD 100 means listed textiles were tested for certain harmful substances against that standard. It does not mean the mattress is organic, medical grade, or free of all chemicals. Check which part of the bed the certificate covers.

Used mattresses can hide stains, wear, pests and missing fire labels. You cannot wash a foam or spring core like a sheet. Many people skip used mattresses. If you still look, check the law label, sag, smell and stains, then use a washable protector.

Follow the manufacturer label first. A common UK care pattern with no instructions is weekly rotation for the first three months, then monthly thereafter, to slow uneven settlement (body impressions).

Measure stairs and doorways before ordering — do not fold most spring mattresses. Book council bulky waste, a recycling centre slot or retailer collection before delivery day. Same-day take-back is not automatic.

Use low-moisture spot cleaning only. Saturating memory foam traps liquid in the foam structure and dries slowly. Blot spills, use mild or enzymatic cleaners sparingly, and rely on a washable protector to prevent stains.

BS 7177 is the British Standard commonly referenced for resistance to ignition of mattresses and related products. Labels indicate the flammability grade for intended use. It does not make a mattress fireproof. BedGuide explains labelling for education — check the product mark for give.

TOG measures thermal resistance: higher TOG means more insulation. UK households often use roughly 4.5 TOG for summer, 10.5 TOG as a year-round middle, and 13.5+ TOG for cold rooms — but comfort is personal and room temperature matters more than a single “correct” number.

TOG (Thermal Overall Grade) measures thermal resistance of a duvet: higher TOG means greater insulation. One TOG equals 0.1 m²·K/W under standard test conditions.

GSM means grams per square metre. It measures fabric or fibre weight. Higher GSM can feel denser. It does not tell you mattress spring support or overall quality by itself.

ILD (or IFD) measures foam hardness — the force needed to indent foam a standard amount. Higher ILD means firmer foam. Density (kg/m³) is separate and relates more to durability. Overall mattress firmness also depends on thickness, layering and the base.

Roll-together is when partners drift toward a shared low point in the mattress centre. Linked open-coil grids often show more of this effect than independently pocketed springs. Soft comfort layers can still create centre sink on any construction.

Zip-and-link joins two matching mattresses with a zip or linking strip so they form one wider surface that can be separated for stairs, storage or dual adjustable bases. Super King width is often created from two Singles.

In UK shop labels, a combination mattress usually means a hybrid: pocket springs topped with foam, latex or fibre comfort layers. The name is older catalogue language for the same layered architecture now commonly called hybrid.

Foam encapsulation is a high-density foam border around a spring unit that stiffens the mattress perimeter and reduces edge collapse when sitting or sleeping near the side.

New foam and adhesives can release a temporary odour called off-gassing as residual compounds leave the polymer. Smell usually fades over days to a few weeks with ventilation. Persistent irritation warrants fresh air and professional health advice if symptoms continue — BedGuide explains the mechanism, not medical risk.

Use a washable mattress protector, wash sheets and pillowcases often on the hottest safe cycle for that fabric, dry bedding fully, and keep bedroom humidity in check. “Hypoallergenic” mattresses are not a complete plan. This is hygiene literacy, not medical treatment.

House dust mites commonly inhabit mattresses and bedding where warmth, humidity and shed skin scales coincide. Hypoallergenic covers reduce allergen exposure through barrier fabrics; they rarely sterilise a mattress completely.
