Key benefits
- Fits compact rooms: At 3ft wide it slots into box rooms and loft conversions with sloped ceilings, leaving floor space free for a desk or wardrobe.
- Full-depth comfort in a small footprint: The single keeps the complete 25cm build, so a lone sleeper gets the same close-moulding, pressure-spreading feel as the larger sizes.
- Suits a spare room that earns two jobs: In a room doubling as an office, the narrow footprint keeps the desk usable while giving guests a genuinely supportive firm bed.
- Firm support for growing teens: The extra firm feel gives heavier teenagers and adult guests solid spinal support, which softer children's mattresses often lack.
- Cheap, easy bedding: Standard single sheets and a 135 x 200cm single duvet fit, and both are the most widely stocked bedding of any size.
This size suits you if...
You sleep alone and want a firm, contouring foam feel without giving a small room over to the bed; you're upgrading a teenager to a supportive adult-quality mattress that will last through growth spurts; or you want a spare room bed that treats guests properly while leaving space for a desk and storage.
Consider another size if...
You're an adult who spreads out at night, or you find 3ft of width restrictive as a permanent bed. The UK small double is 30cm wider at the same length, and we'd recommend it if your room allows.

FAQ's
How big is the Tempur Pro Plus SmartCool Firm in a UK single?
The UK single measures 90 x 190cm, or 3ft x 6ft 3in, with a depth of 25cm. It's the standard one-person size in the UK, so any single frame, standard single fitted sheets and a single duvet will fit without any hunting for unusual bedding.
Is the UK single Tempur Pro Plus SmartCool Firm suitable for a bunk or mid sleeper?
Singles are the standard bunk size, but this mattress is 25cm deep, which is deeper than many raised frames allow. Check that the guardrail still sits high enough above the mattress surface before buying, as most bunk and cabin beds are designed around shallower mattresses.
Is this mattress a good choice for a child's single bed?
For older children and teenagers, yes: the firm support suits growing bodies and the mattress will outlast cheaper options. For younger children it's arguably more mattress than needed, and the slow, sink-in foam feel divides opinion, so a teen upgrading from a childhood bed is the better fit.
What room size do I need for a UK single mattress?
We suggest allowing at least 2.1m x 2.8m of floor space. That leaves room to walk alongside the bed and open drawers or a wardrobe. Because the single is only 90cm wide, it also works under a loft slope or in a shared children's room with two beds and a walkway.
Should I choose the UK single or the UK small double?
The UK single is 30cm narrower than the UK small double, and the two are the same length. A lone adult who values sprawling room, or a guest bed that occasionally sleeps a couple, points to the UK small double. For a teenager's room or anywhere space is tight, the UK single makes more sense.
