Assessed from Spring King's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
The main appeal here is a firm feel that doesn't feel harsh. The pocket springs move independently of one another, which means the mattress responds to your shape and you're less likely to feel your partner shifting about. The memory foam above softens the surface slightly, so you get gentle contouring rather than a board-like finish. The breathable knitted cover helps keep your temperature even through the night. Price honesty: from £239.00 with the range topping out at £529, this is genuinely budget-friendly for a hybrid, and the listing includes free next day delivery. It carries a 4.8 rating from 57 reviews on mattressnextday.co.uk. The 1-year guarantee is shorter than many brands offer.
Key Features & what's inside
- Knitted Cover. A soft knitted cover that's breathable, which means heat can escape rather than build up around you. It helps keep you at an even temperature through the night.
- Memory Foam. This layer adds a soft, cushioning feel, gently moulding to your shape as you settle in. It takes the edge off the firm support underneath.
- Pocket Springs. Individually pocketed springs move independently from one another, so the mattress responds to your body's movements more effectively. In practice, that means support where you need it and less disturbance from a restless partner.

Who's it NOT for?
This is a firm mattress, so lightweight side sleepers may find it puts too much pressure on hips and shoulders. If you want a deep, sink-in memory foam feel, the foam here is a comfort layer rather than the main event. And if a long guarantee matters to you, the 1-year cover is fairly modest.

How firm is the Spring King Pocket Memory Ortho 1500?
It's rated as firm. The memory foam layer softens the surface a little, but the underlying support is on the firmer side, which tends to suit back and front sleepers, and anyone who likes a more supportive feel.
What sizes does the Spring King Pocket Memory Ortho 1500 come in?
Six UK sizes: Small Single, Single, Small Double, Double, King and Super King. Prices range from £239.00 to £529 depending on the size you choose.
How deep is the Spring King Pocket Memory Ortho 1500 mattress?
It's 24cm deep. Standard fitted sheets should work fine at this depth, so there's no need to hunt down extra-deep bedding.
Does the Spring King Pocket Memory Ortho 1500 have a guarantee?
Yes, it comes with a 1-year guarantee. That's shorter than many brands offer, so factor it in if long-term cover matters to you.
Is the Spring King Pocket Memory Ortho 1500 good for hot sleepers?
The breathable knitted cover helps keep you at an even temperature, and pocket springs generally allow more airflow than all-foam designs. There is a memory foam layer, though, which some warm sleepers find holds a little heat.
