Layer Details
- EcoFoam®. A thick layer of 100% recycled and re-engineered foam that responds to your body's natural warmth, moulding to your shape. In practice this means pressure relief exactly where you need it, at your hips and shoulders.
- Reflex Foam. A firm supportive layer that gives the mattress its medium firm feel, which means your spine stays aligned rather than dipping. It's what provides the orthopaedic-style support.
- Memory Foam. A final cushioning layer of memory foam sits nearest to you. It adds a snuggly, softer surface feel over the firmer core.

- A fit for most UK bedrooms: At 135 x 190cm the UK double fits comfortably in rooms where a UK king would crowd the walls; we suggest allowing at least 2.6m x 2.8m.
- Room for two: Two people sharing get 67.5cm each, which works well for couples who sleep close rather than sprawled.
- Foam suits shared sleeping: The EcoFoam® layer moulds to each sleeper individually, so one partner shifting position transfers less disturbance across the bed than a bouncier surface would.
- Bedding is everywhere: Double sheets and a 200 x 200cm duvet are stocked at every price point, handy if you're kitting out a first flat or guest room from scratch.
- Space left for furniture: The narrower footprint leaves room for bedside tables on both sides in an average bedroom, which a UK king often rules out.
This size suits you if...
You're a couple in a typical UK bedroom and want the classic shared size without giving up floor space, you're setting up a guest room that visiting couples will use, or you're furnishing a first flat and need a proper two-person bed that leaves room for a wardrobe and drawers.
Consider another size if...
You and your partner both like space to spread out, since 67.5cm each is snug for restless sleepers. We'd recommend the UK king instead: it's 15cm wider and 10cm longer, giving 75cm each, and needs a room of at least 2.7m x 2.9m.

Is the UK double MattressNextDay Classic big enough for a couple?
Yes, with a caveat. At 135cm wide it gives two sharers 67.5cm each, and the memory foam surface absorbs movement well, so a partner turning over is less noticeable. If either of you sleeps starfish-style, though, the UK king offers 75cm each and may be the calmer choice.
What room size do I need for this mattress in a UK double?
We suggest a room of at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That allows you to open drawers and walk round the bed, and in most average bedrooms it leaves space for bedside tables on both sides.
Should I get the MattressNextDay Classic in a UK double or a UK king?
It comes down to your room and how you sleep. The UK double is 15cm narrower and 10cm shorter than the UK king, so it suits smaller bedrooms and couples who sleep close. If you have at least 2.7m x 2.9m and want more personal space, size up to the UK king.
Is the UK double a good size for a guest room?
It's the most flexible guest room choice, since it accommodates visiting couples as well as solo guests, and the medium firm feel of this mattress suits a wide range of sleepers for short stays. Double bedding is also cheap and easy to find, which keeps the whole setup affordable.
What bedding fits the MattressNextDay Classic UK double?
Standard UK double bedding: double fitted sheets and a 200 x 200cm double duvet. The mattress is 20cm deep, so regular fitted sheets will tuck under without a struggle, and the knitted cover is machine washable, which makes it easy to keep fresh between guests or seasons.
