Assessed from Sleep Story's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
This mattress makes sense if you want natural fillings and a proper firm feel without a premium price tag. The pocket springs move independently, which means support that follows the shape of your body rather than pushing back as one flat surface. Above them sits a 3-inch layer of Reflex Soft foam, so the firm tension is softened slightly at the surface, a little give where your shoulders and hips land. Silk and cashmere in the upper layers help with temperature and add a touch of comfort you can feel through the cover. Add the 20-year guarantee and delivery within 14 days, and it is a straightforward, low-risk buy for a smaller bed.
Key Features & what's inside
- 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.

Who's it NOT for?
This is a firm mattress, so lightweight side sleepers may find it presses on shoulders and hips rather than letting them sink in. Sizes only run from Small Single to Small Double, so couples wanting a standard double or king will need to look elsewhere. Anyone after a plush, sink-in feel should also pass.
Sleep Story Natural Comfort Firm Mattress
How firm is the Sleep Story Natural Comfort mattress?
Sleep Story offers this mattress in soft or firm tensions, and this version is the firm one. Firm suits back and front sleepers and those who prefer to sleep on top of the mattress rather than in it, although lighter side sleepers may find it a little unforgiving.
What is the Sleep Story Natural Comfort Firm mattress made of?
It is a hybrid: pocket springs paired with reflex foam and natural fillings, including a 3-inch Reflex Soft foam comfort layer. The upper layers use silk, polyester, cashmere and viscose, so you get natural breathability at the surface with sprung support beneath.
Does the Sleep Story Natural Comfort Firm mattress have a guarantee?
Yes, it comes with a 20-year guarantee, which is a long span by any measure and longer than most brands offer. That gives you real reassurance about durability, with the usual expectation that you look after the mattress properly.
What sizes does the Sleep Story Natural Comfort Firm come in?
It is available in UK Small Single, Single and Small Double, with prices ranging from £449 to £549. There is no standard double or king option, so it is best suited to children's rooms, guest rooms and smaller spaces.
How deep is the Sleep Story Natural Comfort Firm mattress?
It is 23cm deep, a fairly standard depth that should fit most fitted sheets without any trouble. Delivery is quoted within 14 days, with a Premium Delivery Service available at £39 for mattresses.
