Key benefits
- Room for two: At 135cm wide you get 67.5cm each for two people sharing, enough for most couples who sleep reasonably close.
- Fits typical UK rooms: We suggest a room of at least 2.6m x 2.8m, which most double bedrooms in flats and terraces comfortably clear.
- Space for bedside tables: Because the UK double is 15cm narrower than the UK king, many rooms that couldn't take a king still allow a table on each side.
- Easy to dress cheaply: Double sheets and 200 x 200cm duvets are sold everywhere at every price, which suits a budget-focused mattress like this one.
- Simple to compare: The double is the most common UK size, so the prices shown on this page give you a clear like-for-like benchmark against other budget mattresses.
This size suits you if...
You share the bed every night and want the traditional couples' size, or you sleep alone and like room to stretch out, perhaps with a pet claiming a corner. It also fits if you're furnishing a first flat or a whole house on a budget and need a dependable size that keeps costs down, both on the mattress and on bedding.
Consider another size if...
You and your partner keep waking each other, or one of you sleeps in a starfish. With 67.5cm each for two people sharing, the UK double can feel snug; if your room allows, we'd recommend the UK king instead.

FAQ's
Is the Emma Essential double big enough for a couple?
For most couples, yes. The UK double gives 67.5cm each for two people sharing, which has been Britain's standard shared size for generations. If either of you is broad-shouldered or a restless sleeper, the UK king adds 15cm of width, but it needs a bigger room and costs more, which slightly undermines the point of a budget mattress.
What size room do I need for the Emma Essential 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 leaves space to walk round the bed and open drawers. If your room is a typical second bedroom or first flat with a wardrobe and chest of drawers to fit, the double usually works where a king wouldn't.
What bedding fits the Emma Essential double?
Standard UK double bedding: sheets sized for 135 x 190cm, and a 200 x 200cm double duvet. Because the double is the most widely stocked size in the country, you'll find bedding at every price point, which keeps the total cost down if you're kitting out a whole home at once.
Should I get the Emma Essential in a double or a king?
It comes down to room size and sleeping style. The UK double is 15cm narrower than the UK king, so it fits rooms where a king would crowd out bedside tables. Couples who value personal space tend to prefer the UK king; couples in typical UK bedrooms, or solo sleepers, are usually well served by the double.
Will a double mattress get up the stairs in an older house?
Usually, yes. Foam mattresses like the Emma Essential arrive rolled and boxed, which makes turning stairs in older terraces and tight new build landings far easier than manoeuvring a rigid sprung double. Once it's in the room, unbox it near the bed frame, as it expands quickly.
