Assessed from Sleep Story's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
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, £499 to £699 is not the cheapest hybrid around, but the edge support and that guarantee justify the step up. Delivery is within 14 days, with a Premium Delivery Service at £39 for mattresses.
Key Features & what's inside
- 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.

Who's it NOT for?
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 fans of very tall, hotel-style mattresses should look elsewhere.
Sleep Story Ergo Deluxe Mattress
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 Premium Delivery Service is available for mattresses at £39.
What sizes does the Sleep Story Ergo Deluxe come in?
Six UK sizes: Small Single, Single, Small Double, Double, King and Super King. Prices range from £499 to £699 depending on the size you choose.
