Layer Details
Gel-infused layer
A temperature regulating gel-infused layer tops the mattress and disperses excess body heat, which means you should stay more comfortable if you tend to sleep warm.
Dual-layer pocket spring core
The core has 1000 pocket springs topped with 2000 mini table pocket springs, each in its own cloth sleeve. Because they move independently, you get supportive comfort with less disturbance from a partner.
Layer details from archerssleepcentre.co.uk product page, October 2026.
Key benefits
- Room for bedside tables: At 135cm wide, the UK double usually leaves enough floor for a bedside table on each side, so neither of you has to climb over the other at night.
- Sides you can actually use: With 67.5cm each, couples tend to sleep closer to the edges, and the foam encapsulated border means those outer few centimetres should feel supportive rather than sloping away.
- Less disturbance in a shared bed: The 1000 pocket springs and 2000 mini springs move independently, which means a partner turning over at 3am should be felt a little less on your side.
- Cooler for two bodies close together: Two people on a UK double generate more shared warmth than on wider sizes, so the gel-infused layer that disperses body heat makes a sensible pairing here.
- Easy bedding to find: Standard double sheets and a 200 x 200cm double duvet fit, although at 28cm deep you should check that fitted sheets have deep enough pockets.
This size suits you if...
You share the bed with a partner and want a proper couples' size in a bedroom of ordinary proportions, or you're kitting out a guest room for visiting couples. It also suits a first flat or second bedroom, where the bed has to sit alongside a wardrobe and drawers rather than fill the room.
Consider another size if...
One of you sprawls, or you keep catching each other's elbows. If your room is at least 2.7m x 2.9m, we'd recommend the UK king instead.

FAQ's
Is the Sweet Dreams Optima Gel Pocket 3000 UK double big enough for two people?
For most couples, yes. The UK double gives you 67.5cm each, which is snug if either of you sleeps starfished, but workable for two people who mostly stay on their own side. The foam encapsulated border helps here, because sleepers on a UK double often end up nearer the edge.
What size bedroom do I need for a UK double Optima Gel Pocket 3000?
We suggest at least 2.6m x 2.8m for a UK double. Around 3m x 3m is more comfortable, and gives you space for bedside tables on both sides plus room to open a wardrobe door without squeezing past the bed.
Should I get the UK double or UK king Sweet Dreams Optima Gel Pocket 3000?
The UK double is 15cm narrower and 10cm shorter than the UK king, which works out at 7.5cm less each for two sharing. If your room is at least 2.7m x 2.9m and either of you is tall or restless, the UK king is worth the extra floor space.
How much bigger is a UK double than a UK small double mattress?
The UK double is 15cm wider than the UK small double, and both are the same length. That extra width matters most when two adults share every night; the UK small double, which we suggest for rooms of at least 2.4m x 2.8m, is better kept for solo sleepers or occasional guests.
What is a UK double mattress size in feet?
A UK double measures 4ft 6in x 6ft 3in, or 135 x 190cm. The Optima Gel Pocket 3000 is 28cm deep, so when you buy fitted sheets for the UK double, look for deep pockets rather than a standard shallow fit.
