Layer Details
- Dunlopillo® Plus Sleep Surface. A cooling fabric that stays around 1°C below your body temperature, which means the surface should feel fresher when you get in. A small detail, but a welcome one if you tend to overheat.
- Natural Talalay Latex. 100% natural Talalay latex that contours to your body, so you get pressure relief without losing the firm support underneath. It is also hypoallergenic and highly breathable, a sensible pairing for allergy sufferers and warm sleepers alike.
- VENTRA™ Core Performance System. An aerated foam core engineered to boost airflow through the mattress. In practice, this means heat has somewhere to go rather than building up beneath you overnight.

- Fits compact rooms: At 90cm wide it needs just 2.1m x 2.8m of floor space by our guidance, leaving room for a desk or wardrobe in a smaller bedroom.
- Suits raised frames: The 19.5cm depth sits comfortably within most bunk, cabin and mid-sleeper guard rails, though check your frame's stated maximum before ordering.
- Built for the long haul: Natural Talalay latex is known for lasting well, useful in a single that may carry a child through their teens or serve years of guest duty.
- Cooler for warm sleepers: The aerated core and cooling sleep surface give heat somewhere to go, welcome in box rooms and loft spaces that warm up quickly.
- Easy, cheap bedding: Standard single sheets and a 135 x 200cm single duvet fit, the most widely stocked and affordable bedding of any UK size.
This size suits you if...
You want a firm, supportive mattress for one person: a heavier teen or adult sleeping solo, a spare room that needs to impress occasional guests, or a raised frame where the slim 19.5cm depth keeps the guard rail doing its job. It also suits allergy sufferers furnishing a child's or student's room, since the natural Talalay latex is hypoallergenic.
Consider another size if...
You're an adult who wants space to stretch out, or you share the bed even occasionally. The UK double is 45cm wider at the same length, and we suggest allowing at least 2.6m x 2.8m of floor space for it.

Will the Dunlopillo Firmrest UK single fit a bunk bed or mid sleeper?
In most cases, yes. The UK single measures 90 x 190cm, the standard footprint for UK bunk and mid-sleeper frames, and the 19.5cm depth is slimmer than many hybrids, which helps keep the guard rail at a safe height on a top bunk. Check your frame's maximum mattress depth before buying, as limits vary.
Is the Firmrest UK single a good choice for a child's room?
The size is right: at 90cm wide it leaves floor space for a desk and toy storage in even a small bedroom, and the hypoallergenic latex suits young allergy sufferers. The feel needs more thought. This is a genuinely firm mattress, and lightweight children, especially side sleepers, may find it a little unyielding.
What room size do I need for the Firmrest in a UK single?
We suggest allowing at least 2.1m x 2.8m of floor space. That gives you a walkway alongside the bed and room to open drawers or a wardrobe. It also makes the UK single one of the few sizes that works under a loft conversion slope or in a spare room that doubles as an office.
Is a UK single Firmrest big enough for an adult?
For one adult, usually yes. At 90 x 190cm, or 3ft x 6ft 3in, it's the standard UK one-person size, and the firm latex build suits heavier solo sleepers who need proper support. If you're restless or simply like room to spread out, the UK small double is 30cm wider at the same length.
Does the UK single Firmrest work for a guest room?
It's a practical fit, particularly where you want two beds rather than one so guests aren't forced to share. Natural Talalay latex holds its shape well through irregular use, so a guest bed that sits empty for weeks shouldn't suffer for it. Bear in mind the firm feel: guests who prefer a soft, cradling surface will notice.
