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.

- The classic shared size: At 135 x 190cm the UK double gives two sleepers 67.5cm each, which works well here because firm Talalay latex keeps movement from travelling across the bed.
- Fits rooms a king would crowd: We suggest at least 2.6m x 2.8m for a UK double, so bedside tables on both sides remain realistic in an average British bedroom.
- Firm support for two different bodies: The 100% natural Talalay latex contours to each sleeper individually, which means a heavier partner and a lighter one both get proper push-back rather than a shared dip.
- Cooler for couples: Two people sharing 135cm generate more heat than one, so the cooling sleep surface and aerated VENTRA core have more to do in this size, and do it well.
- Easier to manoeuvre than the bigger sizes: At 19.5cm deep and in the UK double footprint, this mattress turns tight staircases and narrow landings more easily than the UK king or UK super king would.
This size suits you if...
You share the bed every night and want a firm, responsive surface in a size that leaves your bedroom usable, or you sleep alone and like room to spread out, perhaps with a dog or cat claiming a corner. It also suits a guest room that hosts visiting couples, since the firm latex feel divides opinion less than a soft mattress and the size accommodates two without dominating the room.
Consider another size if...
You and your partner both like space, your room measures at least 2.7m x 2.9m, and 67.5cm each feels tight. The UK king is 15cm wider and 10cm longer than the UK double, and we'd recommend it instead.

Is the Dunlopillo Firmrest UK double big enough for two adults?
Yes, with a caveat. Two people sharing get 67.5cm each, less than a UK single apiece, so it suits couples who don't mind sleeping fairly close. The Firmrest helps here: firm Talalay latex responds quickly and doesn't let one sleeper's movement roll the other towards the middle. Broad-shouldered couples may still prefer the UK king.
What room size do I need for the Dunlopillo Firmrest double?
We suggest a minimum of 2.6m x 2.8m for a UK double, with around 3m x 3m the comfortable norm. That allows walking space on both sides and, in most rooms, bedside tables too. If your bedroom stretches to at least 2.7m x 2.9m, the UK king becomes an option worth weighing.
Will the Firmrest UK double fit up a narrow staircase?
Latex mattresses don't arrive rolled the way boxed foam does, so measure your access first. The good news is the UK double is the most forgiving couples' size to move: at 135 x 190cm and 19.5cm deep it turns tight landings and older terrace staircases more readily than the wider, longer UK king would.
Should a couple choose the Firmrest in a double or a king?
It comes down to your room. The UK double is 15cm narrower and 10cm shorter than the UK king, and needs 2.6m x 2.8m against our suggested 2.7m x 2.9m for the UK king. If space allows and you value stretching out, size up. If the room is typical of a UK home, the UK double keeps it liveable.
Is the UK double Firmrest a good guest room mattress?
It's a sensible choice. The size handles visiting couples, and the firm, quick-responding latex feel tends to work for guests you can't ask about preferences in advance. It's also hypoallergenic, which matters when different people use the bed. It's a serious spend for occasional use, though the materials are built to last.
