Layer Details
- Silk. A 270 GSM layer of silk sits at the top, which means a naturally breathable surface that helps move heat and moisture away from you. It gives the sleeping surface a softer, more luxurious first impression than the firm tension might suggest.
- Polyester. Beneath the silk is a 270 GSM polyester layer. It adds a little cushioning and helps the surface layers keep their shape over time.
- Reflex Soft foam. A 3-inch layer of Reflex Soft foam provides the main comfort padding. It softens the feel of the springs below, so you get pressure relief at the surface without losing the firm support underneath.
- Pocket springs with reflex foam. The base combines pocket springs with reflex foam and natural fillings. Each spring moves on its own, which means support adjusts to your weight across the mattress rather than as one rigid block.

- Space to spread out alone: At 30cm wider than the UK single, you can sleep diagonally or starfish without an arm dropping off the edge.
- Fits rooms a double would crowd: Being 15cm narrower than the UK double often decides whether a wardrobe door or bedroom door still opens freely beside the bed.
- Full adult length: The UK small double is the same length as the UK double, so a grown adult gets the same legroom as on a standard double.
- Firm support for a heavier frame: Pocket springs with a firm tension give a solo adult steady support across the full width, with a little surface give from the foam above.
- Workable for occasional guests: A couple visiting for a weekend will manage comfortably enough, which suits a spare room that sits empty most of the week.
This size suits you if...
You sleep alone and want more room than a single allows, your bedroom is compact enough that a 4ft 6in frame would squeeze the floor space, or you are furnishing a spare room where couples stay for the odd night.
Consider another size if...
Your room is under our suggested minimum of 2.4m x 2.8m. The UK single would suit you better; we suggest at least 2.1m x 2.8m for that size.

Is the Sleep Story Natural Comfort Firm small double big enough for a couple?
For occasional stays, yes. For every night, most couples will find it tight, because the UK small double is 15cm narrower than the UK double. This mattress does not come in a UK double or larger, so couples sharing nightly would need a different model altogether.
What size bedroom do I need for a UK small double Sleep Story mattress?
We suggest allowing at least 2.4m x 2.8m for a UK small double. That leaves space to walk around the bed and open doors and drawers. In a narrower room, the UK single needs less floor space, and we suggest at least 2.1m x 2.8m for it.
Is the UK small double the largest size of the Sleep Story Natural Comfort Firm?
Yes. The range runs from UK small single through UK single to UK small double, so the UK small double is the biggest option. If you want this firm natural hybrid with the most room possible, the UK small double is the size to choose.
Should an older teenager have the UK small double or the UK single?
If the room can take it, the UK small double gives a growing teenager 30cm more width at the same length as the UK single. Where floor space is tight, the UK single frees up room for a desk, and we suggest at least 2.1m x 2.8m for it.
Will a 4ft small double fit a loft conversion bedroom?
Often, yes, because the UK small double measures 4ft x 6ft 3in, which is narrower than a standard double. In a loft with sloping ceilings, check that the width leaves you room to stand on the side of the bed where the ceiling is highest.
