Layer Details
- Cover. A QuickRefresh™ cover with SmartCool™ technology, designed to help the surface feel cooler when you get in. That matters with foam mattresses, which can otherwise run a little warm.
- Core. TEMPUR® Advanced Material, a slow-response foam that moulds to your body under heat and pressure. You sink in gradually rather than bouncing, which spreads your weight and eases pressure points.

- Fits compact rooms: At 90cm wide, it slots into box rooms, loft conversions with sloping ceilings and student bedrooms where a wider mattress simply wouldn't leave a walkway.
- Full support for one: TEMPUR® Advanced Material moulds to your shape rather than springing back, which means a solo sleeper gets the same firm, pressure-relieving support as the bigger sizes.
- A serious guest bed: For a spare room that doubles as an office, it gives occasional guests a proper firm mattress in a footprint the desk can live alongside.
- Cheap, easy bedding: Single sheets and duvets are the most widely stocked and lowest priced of any size, so dressing this mattress costs less year after year.
- Cooler surface, small footprint: The QuickRefresh™ cover with SmartCool™ technology aims to keep the surface cooler, useful because dense foam can hold warmth, even in a snug room.
This size suits you if...
You sleep alone and want Tempur's firm, contouring support without giving floor space to a wider bed, you're setting up a spare room that spends most of its life as an office, or you're buying for an older teen who needs proper support and a room that still fits a desk and wardrobe.
Consider another size if...
You're an adult who spreads out at night, or you find 90cm leaves your elbows off the edge. The UK small double, which is 30cm wider than the UK single, would suit you better.

What are the dimensions of the Tempur Pro SmartCool Firm UK single?
It measures 90 x 190cm, which is 3ft x 6ft 3in. That's the standard UK one-person size, so it fits any regular single bed frame and takes standard single sheets and a single duvet, typically 135 x 200cm.
Can I use the Tempur Pro SmartCool Firm UK single on a bunk or mid sleeper frame?
The 90 x 190cm footprint matches standard bunk and mid sleeper frames, and at 21cm deep it's slimmer than many foam mattresses. Do check your frame's maximum mattress depth first: guard rails need to sit well above the sleep surface, and some bunk frames specify a lower limit than 21cm.
Is the UK single Tempur Pro SmartCool Firm a good choice for a child?
We'd hesitate for younger children. The feel is described as extra firm, and lighter bodies may not sink in enough for the foam to mould properly. It makes more sense for older teens and adults who want firm support. It's also a significant spend for a bed a child will outgrow.
What room size do I need for a UK single mattress?
We suggest allowing at least 2.1m x 2.8m of floor space. At 90cm wide, this size works in loft conversions where the bed has to sit under the slope, and in rooms where a desk or wardrobe competes for space.
Should I get the Tempur Pro SmartCool Firm in a UK single or a UK small double?
The UK single is 30cm narrower than the UK small double. If you're a solo adult who likes room to stretch, and your floor space allows it, that extra width is noticeable every night. Where the room is tight, or the bed is for a teen or guests, the UK single is the sensible pick. Compare the retailers listed on this page for current pricing.
