The Sleep Story Ergo Deluxe pairs ErgoSense foam with pocket springs, 1,000 of them in the king size, which means pressure relief on top and springs that respond to you and your partner independently underneath. Sleep Story describes the medium feel as ideal for most sleepers, and it comes with a 20-year guarantee, longer than most brands offer. It's available in six UK sizes from Small Single to Super King. A sensible middle-of-the-road choice, although anyone who wants a distinctly firm or plush feel should look elsewhere.

Why should you choose this mattress?
The main appeal is balance at a fair price. The ErgoSense foam layer relieves pressure, which means less of that pins-and-needles feeling on hips and shoulders, while the pocket springs support spinal alignment. DynamicEdge® side support stiffens the perimeter, so you can use the full width of the bed without feeling you might roll off, handy for couples on a Double. The mattress is hypoallergenic, and the 20-year guarantee shows real confidence in how it will hold up. Yes, it's not the cheapest hybrid around, but the edge support and that guarantee justify the step up. Delivery is within 14 days, with a paid Premium Delivery Service for mattresses.
Key features & layer details
Cover
A breathable stretch fabric cover. It flexes with the layers beneath, so you feel the foam's contouring rather than a taut surface.
Foam
High-performance ErgoSense foam relieves pressure and promotes healthy blood circulation, which means less tossing and turning to relieve numb spots. It's the layer that gives the mattress its medium, cushioned feel.
Springs
Individually pocketed springs, 1,000 of them in the king size, move independently rather than as one unit. That means better spinal alignment and less disturbance when a partner shifts in the night.
Support
DynamicEdge® active side support firms up the perimeter to maximise the usable sleep surface and prevent roll-off. Useful if you sit on the edge to dress, or share a smaller bed.

Best suited for?
Couples
Individually pocketed springs move independently, so you feel less disturbance when a partner shifts, and DynamicEdge side support lets you both use the full width of the bed.
Allergy sufferers
The copy describes the mattress as hypoallergenic, which makes it a sensible pick if you want a bed that suits sensitive sleepers.
Combination sleepers
Medium firmness with a stretch cover that flexes with the foam gives a balanced, cushioned feel that suits people who change position through the night.
Side sleepers
ErgoSense foam relieves pressure, which means less of that pins-and-needles feeling on hips and shoulders when you lie on your side.
If you prefer a firm mattress, perhaps because you're a heavier back sleeper, this medium feel may let you sink a little more than you'd like. Equally, anyone after a deep, plush pillow-top sensation won't find it here. At 23cm it's a standard depth, so if you prefer a very tall, hotel-style mattress, this might not be the best choice.
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
Is the Sleep Story Ergo Deluxe firm or soft?
It's a medium feel, which Sleep Story describes as ideal for most sleepers. That means a balance of cushioning from the ErgoSense foam and support from the pocket springs, rather than a distinctly firm or soft surface.
How many springs does the Sleep Story Ergo Deluxe have?
The king size contains 1,000 individually pocketed springs. Pocketed springs move independently of each other, which means the mattress responds to your shape and reduces motion transfer between partners.
What guarantee comes with the Sleep Story Ergo Deluxe?
Sleep Story offers a 20-year guarantee on this mattress, which is longer than most brands offer and a decent sign of confidence in its durability.
How long does Sleep Story Ergo Deluxe delivery take?
It's delivered within 14 days. A paid Premium Delivery Service is available for mattresses.
What sizes does the Sleep Story Ergo Deluxe come in?
Six UK sizes: Small Single, Single, Small Double, Double, King and Super King.
