Layer Details
- Knitted cover. A soft knitted cover that adds a cosy, slightly warm surface feel. The knit structure is designed to let air pass through, which helps the mattress breathe overnight.
- Soft White Fibres. Soft synthetic e-Fibre fillings that give the top of the mattress its cushioned feel. They're designed to be resilient, holding their shape rather than flattening quickly.
- 3D spacer. A spacer layer that improves airflow through the mattress. In practice, that means less heat building up around you as you sleep.
- Pocket Springs. Springs sit in individual cloth pockets, so each one responds to your body independently. That gives more tailored support along your spine and reduces the ripple effect when someone else moves.

- The classic shared footprint: At 135 x 190cm (4ft 6in x 6ft 3in), the UK double gives couples the traditional two-person bed in a shape most UK rooms accept comfortably.
- 67.5cm each for two sharing: Two people get 67.5cm of width apiece, which means enough space to sleep side by side, provided neither of you is a dramatic starfish.
- Springs that keep movement local: The 1,000 pocket springs respond individually, which matters most in a double: with 67.5cm each, your partner turning over is less likely to wake you.
- Room left for the rest of your furniture: We suggest at least 2.6m x 2.8m, so a typical second bedroom or first flat still fits a wardrobe and drawers around it.
- Cool sharing at close quarters: Two bodies in a double generate real warmth, and the all-fibre, no-foam build with its airflow spacer layer helps that heat escape rather than build up.
This size suits you if...
You're a couple happy with the traditional shared size, and your bedroom sits around the 2.6m x 2.8m minimum we suggest, where a UK king would crowd out bedside tables on both sides. It also suits you if you sleep alone but want space to sprawl, or a corner spare for a dog or cat, or you're kitting out a guest room that visiting couples will use.
Consider another size if...
Your room comfortably exceeds 2.7m x 2.9m and you both want more personal space. The UK king is 15cm wider and 10cm longer, and we'd recommend it instead, especially if either of you is tall.

Is the Jay-Be 1000 e-Pocket in a UK double big enough for a couple?
For most couples, yes. You each get 67.5cm of width, and the 1,000 individually pocketed springs limit how much one person's movement travels to the other side. If you're both broad-shouldered or restless sleepers, the extra width of the UK king version would make sharing noticeably easier.
What size room do I need for the Jay-Be 1000 e-Pocket double?
We suggest allowing at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That leaves walking space on both sides and room for bedside tables, which matters in older terraces and compact new builds where every centimetre of floor counts. These are our recommendations rather than Jay-Be's.
Should I choose the Jay-Be 1000 e-Pocket in a double or a king?
The UK double is 15cm narrower and 10cm shorter than the UK king. If your room meets the 2.7m x 2.9m we suggest for a UK king and you share every night, size up. If floor space is tight, the UK double keeps the room usable.
Is the UK double a sensible choice for a guest room?
Yes, arguably the ideal one. It accommodates visiting couples as well as solo guests, and this mattress's simple, breathable fibre-and-spring build suits occasional use well. Its price sits at the budget end of pocket sprung mattresses, so it's an easy pick when you're furnishing a whole home and the budget is stretched thin.
Where can I compare prices for the Jay-Be 1000 e-Pocket in a UK double?
Use the price table on this page. The prices shown here are updated as retailers change them, so it's a more reliable guide than any figure written into the text. Availability of individual sizes shifts too, so check the double specifically rather than assuming it matches other sizes.
