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
- Room to spread out alone: At 30cm wider than the UK single, you can sleep diagonally or starfish without an arm hanging off the side.
- Fits where a double won't: Being 15cm narrower than the UK double can mean the wardrobe door opens fully, or there's still space for a bedside table.
- Usable right to the edge: The pocket springs support the whole surface, which means a narrower bed still gives you its full width to lie on, edges included.
- Easy to dress: Small double fitted sheets fit, and a standard double duvet covers it, so bedding is simple to find in UK shops.
- Cushioned top for guests: The pillow top with micro springs gives a cushioned surface on a medium-rated base, so visiting couples get a comfortable night without a dedicated double.
This size suits you if...
You sleep alone and like room to roll over without meeting the edge, or you're setting up a compact spare room where a couple stays now and then. It also fits a teenager who has outgrown a single in a bedroom that can't give up much floor.
Consider another size if...
You share the bed with a partner every night, or you want more length than 190cm. We'd recommend the UK king instead, which gives 75cm each for two sharing; we suggest at least 2.7m x 2.9m.

FAQ's
Will a Sleepeezee Zenith 4500 small double fit in a box room?
For a UK small double, we suggest a room of at least 2.4m x 2.8m. That leaves enough floor to walk round the bed and open a door. In a very tight box room, measure where the door swings before you commit, since width is usually what decides it.
Can two people sleep on the Zenith 4500 in a UK small double?
Yes, for occasional stays, but it's snug for nightly sharing. The UK double is 15cm wider and gives 67.5cm each for two sharing. The edge-to-edge spring support helps on a small double, because neither of you is pushed onto a soft rim.
Is a UK small double big enough for a teenager moving up from a single?
For most, yes. It's 30cm wider than the UK single at the same 190cm length, so the extra space comes in width rather than length. A very tall teenager who is still growing may want the UK king, which is 10cm longer, if the room allows.
What bedding fits a Zenith 4500 small double?
Use small double (4ft) fitted sheets with a standard double duvet. At 35cm deep, look for fitted sheets with deep pockets so the corners stay put on the pillow top.
Zenith 4500 small double or double for a loft conversion?
In an attic room with sloping ceilings, the UK small double is often the better fit, as it's 15cm narrower than the UK double and leaves more headroom beside the bed. The mattress is 35cm deep, so check the sleeping height against the slope too.
