Layer Details
Breeze 3D knit cover
A knitted cover that's up to 40% more breathable than standard fabrics, which means air moves more freely at the surface.
Plush pillow top with micro springs
A plush pillow-top layer with micro springs that adds a softer surface. It gives the mattress a cushioned feel on top of its medium rating.
Double graphite memory foam
Two layers of graphite-infused memory foam that help draw heat away from the body, so you get foam comfort with less heat build-up.
Pocket spring unit
Individually wrapped pocket springs giving responsive support and edge-to-edge support, so the whole surface feels usable.

Key benefits
- Fits an ordinary bedroom: We suggest a room of at least 2.6m x 2.8m, so a modest second bedroom can still hold a wardrobe and a chest of drawers beside it.
- Usable right to the edge: Pocket springs support to the edges, which means whoever sleeps nearer the wall or the door keeps their full 67.5cm rather than a soft, sloping rim.
- Less heat build-up when sharing: Two layers of graphite memory foam help draw heat away from the body, which helps when two people share 135cm of width on a warm night.
- Bedding is easy to find: Standard double sheets and a 200 x 200cm double duvet fit, so making up a guest room for visiting couples needs nothing out of the ordinary.
This size suits you if...
You share the bed with a partner in a bedroom of everyday UK proportions and still want a bedside table on each side, or you're setting up a guest room where couples will stay, or you sleep alone and like room to spread out.
Consider another size if...
You and your partner both sprawl, or one of you wants more length and width. We'd recommend the UK king instead, which gives 75cm each; allow at least 2.7m x 2.9m.

FAQ's
Is the Sleepeezee Zenith 4500 UK double big enough for two adults?
For most couples, yes. The UK double gives 67.5cm each, and because the pocket springs support to the edges, the outer part of the bed stays usable. If either of you sleeps in a starfish shape, the UK king gives 75cm each, which is a noticeable step up.
What size bedroom do I need for a Sleepeezee Zenith 4500 double?
We suggest at least 2.6m x 2.8m for the UK double, with around 3m x 3m feeling comfortable. At the smaller end, check you can still fit a bedside table on both sides and open the wardrobe doors before you commit.
Sleepeezee Zenith 4500 double or king: which should couples choose?
The UK double is 15cm narrower and 10cm shorter than the UK king, and gives each sleeper 7.5cm less width. The UK king needs a room of at least 2.7m x 2.9m. If your room clears that comfortably and you value space, size up; if not, the UK double is the sensible fit.
What bedding fits a Sleepeezee Zenith 4500 in a UK double?
Double sheets and a 200 x 200cm double duvet fit. The mattress is 35cm deep, so check the pocket depth on any fitted sheet before buying, as shallower ones may not tuck under securely.
Should I choose a UK double or UK small double Zenith 4500 for a spare room?
If couples will stay, the UK double is 15cm wider than the UK small double, which makes a real difference for two adults. The UK small double suits tighter rooms, where we suggest at least 2.4m x 2.8m, and works better for single guests.
