Layer Details
Soft knitted cover
A soft knitted cover finishes the top of the mattress. It gives you a gentle surface to lie on.
Soft polyester comfort layer
A soft polyester filling sits under the cover. It adds cushioning at the surface, which is part of the pillow top feel.
Staycool Gel
A cooling comfort foam with an open-cell structure. It's there to help the mattress feel cooler while still cushioning you.
ActivFlex spring foam
A profiled, responsive support foam layer. It adds support under the comfort layers, so you aren't sinking straight through.
1400 mini comfort springs
Mini pocket springs sit in the comfort layer. They respond to your body in smaller areas, which adds to the cushioned feel.
1200 traditional pocketed springs
Traditional pocket springs form the core of the mattress. They give the main support underneath you.
Fully encapsulated spring unit
The spring unit sits inside a fully encapsulated foam border. That gives the edges a more stable feel.
Foundation support pad
A foundation pad sits at the base as the foundation for the layers above. It separates the springs from your bed base.

Key benefits
- Room left for everything else: At 3ft x 6ft 3in, the UK single leaves floor space for a desk, wardrobe and toy storage in a child's bedroom, which means the bed doesn't take over.
- Two beds in a guest room: A pair of UK singles lets you host two friends or siblings separately, and our suggested minimum of 2.1m x 2.8m applies to each bed's space.
- Cushioning without going soft: The pillow top and mini comfort springs give a gentle surface, which suits a solo sleeper who wants some give but still needs support from the pocket springs underneath.
- Steadier edges on a narrow bed: A fully encapsulated foam border surrounds the springs, which means the edge feels more stable when you sit down to get dressed or a child perches to read.
- No flipping in a tight room: It's single-sided and no-turn, so in a small bedroom or loft conversion you only need to rotate it, with turning handles to help.
This size suits you if...
You sleep alone and want a medium feel with a little cushioning, your bedroom or loft conversion only has space for a narrow footprint, or you're furnishing a spare room that also serves as a home office and needs a bed that leaves room for a desk.
Consider another size if...
You often sprawl, share the bed with a partner, or want more room to turn over. We'd recommend the UK small double instead, which is 30cm wider; we suggest at least 2.4m x 2.8m for it.

FAQ's
Will a Sleepeezee ActivFlex Response 2600 single fit a bunk bed or cabin bed?
It may not suit every raised frame. The mattress is 27cm deep, and bunk, cabin and mid-sleeper frames often set a maximum mattress depth so the guard rail stays high enough. Check the frame maker's own guidance before buying a UK single for a top bunk or high sleeper.
What size is the UK single ActivFlex Response 2600 in feet?
The UK single measures 3ft x 6ft 3in, or 90 x 190cm. That's the standard UK single size, so it should fit a standard single bed frame or divan without gaps.
How much space do I need for a UK single Sleepeezee pillow top mattress?
We suggest allowing at least 2.1m x 2.8m of floor space for a UK single. That gives you room to get in and out comfortably and still fit furniture such as a bedside table or a small desk.
Is a UK single big enough for an adult?
For one adult who sleeps fairly still, yes, the UK single gives 90cm of width to yourself. If you roll around a lot or like to stretch out, the UK small double is 30cm wider and the same length, so it adds width without needing a longer room.
Do I need deep fitted sheets for a 27cm single pillow top mattress?
At 27cm deep, this mattress is thicker than many basic singles, so check the pocket depth on any fitted sheet before you buy. A single duvet at 135 x 200cm suits the UK single.
