The Sleep Story Natural Comfort Firm is 23cm deep and sits at the accessible end of the natural-materials market. It comes in UK Small Single, Single and Small Double sizes, which makes it a sensible pick for a child's room, a guest bed or a smaller space rather than a main double bed. The 20-year guarantee is unusually long, considerably more than most brands offer, which says something about how the maker expects it to hold up.

Why should you choose this mattress?
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 & 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.

Best suited for?
Guest rooms
The Small Single to Small Double size range suits a spare room, and the 20-year guarantee means it should keep its shape between visits.
Back sleepers
Independent pocket springs adjust to your weight across the mattress, giving firm, even support that keeps your body level while you lie flat.
Warm sleepers
A silk layer on top is naturally breathable and helps move heat and moisture away from you, which keeps the surface feeling fresher overnight.
Eco-conscious buyers
Silk, cashmere and natural fillings in the upper layers give a mostly natural build without the premium price tag usually attached to it.
Front sleepers
The firm feel stops your hips sinking too far, while the 3-inch Reflex Soft foam layer softens the surface a little.
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.
Save on an earlier or ex-display model
Some retailers still sell the earlier version of this mattress, or ex-display and returned stock at a lower price. These are the sizes where it costs less than the current model's best price.

FAQ's
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. 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 paid Premium Delivery Service available for mattresses.
