Layer Details
Stretch knit cover
A soft, pliable stretch knit fabric that lets the fillings beneath contour to your body shape. It adds a gentle first layer of comfort without stiffening the surface.
Boxtop
A boxtop is deeper than a pillowtop and adds extra comfort layers over the springs. You get a plusher top feel, while the medium-firm feel underneath keeps it supportive.
Gel layer
A breathable, responsive gel layer with patented gel bead temperature control. It relieves pressure and disperses excess body heat away from the surface, which suits you if you sleep warm.
Pocket springs
Individual, independent springs that contour to your body shape and minimise partner disturbance. If your partner moves a lot in the night, you should notice less of it.
Foam encapsulated border
A high density foam border surrounds the spring system for edge-to-edge support. It helps prevent the feeling of roll-off, so you can use more of the bed and sit on the edge more comfortably.

Key benefits
- Room for two in a normal bedroom: At 135cm wide, this double sleeps a couple comfortably while still leaving space for bedside tables on both sides in most UK rooms.
- 67.5cm each when sharing: Two people get 67.5cm each across the width, enough for most couples, although restless sleepers may prefer to size up.
- Fits where a king would dominate: We suggest a minimum room of 2.6m x 2.8m, which most British bedrooms clear, so you get a premium mattress without a cramped room.
- Generous for one: Sleeping solo, the full 135cm width is yours, with plenty left over if a dog or cat has claimed a corner of the bed.
- Easy to dress: Standard double sheets and a 200 x 200cm duvet fit this size, and both are stocked everywhere at every price point.
This size suits you if...
You share the bed every night and want the classic couples' size that fits a typical UK bedroom, you sleep alone and like room to stretch out, or you're furnishing a guest room that needs to host visiting couples. It also suits you if your room measures around 2.6m x 2.8m or more, where a wider bed would crowd the walking space.
Consider another size if...
You and your partner both move around at night and 67.5cm each feels tight, or your room comfortably exceeds 2.7m x 2.9m. In either case we'd recommend the UK king instead, which is 15cm wider and 10cm longer.

FAQ's
Is the Kaymed Signature Response Gel Pocket 2500 Boxtop double big enough for two adults?
For most couples, yes. The UK double gives 67.5cm each for two people sharing, which has been the British standard for decades. If either of you is broad shouldered or sleeps restlessly, the UK king adds 15cm of width and 10cm of length, provided your room allows at least 2.7m x 2.9m.
What room size do I need for this mattress in a UK double?
We suggest a minimum of 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That allows bedside tables on both sides and space to open wardrobe doors. If you're measuring a smaller second bedroom or a first flat, sketch the bed alongside the wardrobe and drawers before committing.
Will a UK double version of this mattress fit up narrow stairs?
At 135 x 190cm it's a manageable size for most homes, though a boxtop mattress is on the bulkier side, so measure the turn on the stairs in an older terrace or a tight new build landing before delivery day. Kaymed doesn't publish a weight for this mattress, so check with the retailer if access is tight.
How does the double compare with the small double for this Kaymed mattress?
The UK double is 15cm wider than the UK small double, and the two are the same length. For a couple, that extra 15cm is usually the difference between comfortable and cosy. The UK small double suits a smaller room, where we suggest at least 2.4m x 2.8m.
What are the dimensions of the UK double in feet and inches?
The UK double measures 4ft 6in x 6ft 3in, or 135 x 190cm. Check your bed frame is a standard UK double rather than an EU size before ordering, as EU frames run slightly different dimensions and the mattress will sit awkwardly in the wrong one.
