The Sleep Story Memory Plus is 25cm deep, with a memory foam comfort layer that moulds to your body to relieve pressure, and a Tencel cover, a breathable fibre made from wood pulp. It comes in six UK sizes, from Small Single to Super King. The 20-year guarantee is longer than most brands offer, which suggests some confidence in how the foam will hold up. If you like a bed with a bit of bounce, memory foam's slower, hug-like feel may not be for you.

Why should you choose this mattress?
The main draw here is pressure relief at a fairly gentle price. The memory foam comfort layer moulds to your shape, which means less pressure on your hips and shoulders, something side sleepers in particular tend to feel the benefit of. The Tencel cover helps with moisture, and the mattress is hypoallergenic, a sensible pick if dust or allergens bother you at night. A 20-year guarantee is rare at a mid-range starting price. Delivery carries a charge, with an estimated wait of up to 14 days, so it isn't the quickest or cheapest to arrive, but the starting price keeps the total spend reasonable.
Key features & layer details
Memory foam comfort layer
A deep memory foam comfort layer moulds to your body to relieve pressure. In practice that means a slow, cradling feel that eases weight away from your hips and shoulders.

Best suited for?
Side sleepers
The memory foam comfort layer moulds to your shape, which means less pressure building up under the hips and shoulders when you lie on your side.
Allergy sufferers
A hypoallergenic build and a Tencel cover make this a sensible choice if dust or allergens tend to bother you at night.
Couples
Six UK sizes up to Super King give you room to spread out, and the slow, cradling foam gives each of you a hug-like feel.
Back sleepers
The medium feel and deep memory foam layer cradle the body evenly, which suits lying on your back and gives gentle support without being too hard.
If you sleep hot, all-foam mattresses can hold warmth more than sprung ones, so approach with a little caution despite the breathable Tencel cover. It's also not ideal if you prefer a springy, responsive surface, or if you want a firm mattress: this is a medium feel through and through.
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.
