Choose the Firmrest if you specifically want a firm feel with a little natural give on the surface. Talalay latex responds quickly when you move, which means none of that stuck-in-the-mattress sensation some foams create. It is hypoallergenic and vegan friendly, and Dunlopillo is an NBF-approved manufacturer, so the materials are independently checked. The aerated foam core and cooling sleep surface both work in favour of hot sleepers. Yes, £929 is a lot for a starting price, but the 15-year manufacturer guarantee suggests Dunlopillo expects it to go the distance. Lighter sleepers, or anyone who loves a soft, cradling feel, should look elsewhere. This is unapologetically a firm mattress.
Key Features & what's inside
- 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.

Who's it NOT for?
This is a genuinely firm mattress, so lightweight side sleepers may find it too unyielding at the shoulder and hip. If you prefer a plush, sink-in feel, or you are shopping on a tight budget, the Firmrest is not the right fit. Anyone wanting a deep, hotel-style profile may also find 19.5cm modest.
Dunlopillo Firmrest Latex Mattress
How firm is the Dunlopillo Firmrest mattress?
It is rated firm, and the one owner review on the mattressnextday.co.uk listing backs that up, with the customer preferring it to a mid-firm alternative. The Talalay latex surface adds a little contouring, so it feels supportive rather than hard, but this is a mattress for people who definitely want firm.
Is the Dunlopillo Firmrest good for hot sleepers?
It is well set up for warm sleepers. The sleep surface is designed to stay around 1°C below body temperature, the Talalay latex is highly breathable, and the aerated foam core is built to move air through the mattress. Latex generally runs cooler than memory foam, so hot sleepers should get on well here.
How long is the guarantee on the Dunlopillo Firmrest?
It comes with a Dunlopillo 15-year manufacturer guarantee, which is longer than most brands offer and a reasonable signal of confidence in the natural Talalay latex construction. As with any guarantee, check the terms for what is and is not covered before you buy.
What sizes does the Dunlopillo Firmrest come in?
It is available in UK Single, UK Double, UK King, UK Super King and EU Single, with prices ranging from £929 to £1,759 depending on the size you choose.
Is the Dunlopillo Firmrest suitable for allergy sufferers?
Yes, the natural Talalay latex is hypoallergenic, and the mattress is also listed as vegan friendly. It meets the BS7177: 2008 fire resistance standard and comes from an NBF-approved manufacturer, so the materials and safety claims are independently vetted.
