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 genuine pocket spring support at a price that undercuts much of the market. Each spring works independently, which means better pressure relief around your hips and shoulders and less disturbance from a partner moving about. The medium firm feel suits most back and stomach sleepers, although lightweight side sleepers may find it a little too solid. The polyester fibre fillings are simple rather than plush, but they keep the price down and the mattress hypoallergenic, a real plus if dust triggers your allergies. Free next day delivery to mainland UK sweetens the deal, though some addresses may incur a small fee. The 1 year guarantee is short, so weigh that against the low price.
Key Features & what's inside
- Cover. A breathable Belgian damask fabric cover, which means air can move through the surface rather than getting trapped against you. That helps keep things a little cooler overnight.
- Comfort Fillings. Soft white fibre fillings made from 100% polyester. These give a simple, even comfort layer over the springs rather than a deep, plush feel.
- Support System. Pocket springs mounted in their own separate fabric pockets, so each spring works completely independently of the others. You feel this as support that follows your body's shape, relieving pressure where you need it.

Who's it NOT for?
If you want a plush, sink-in feel, the medium firm tension and simple polyester fillings will likely feel too firm, especially for lightweight side sleepers. Anyone wanting memory foam contouring or a long guarantee should also look elsewhere, as this comes with 1 year of cover rather than the decade some brands offer.

Is the Spring King Pocket Backcare 1500 firm or soft?
It's a medium firm mattress. That tension suits most back and stomach sleepers, giving enough push-back to keep your spine level. Lightweight side sleepers may find it slightly too firm at the shoulder and hip, where a softer surface would let those points sink in more.
How thick is the Spring King Pocket Backcare 1500 mattress?
It's 25cm deep, which fits standard fitted sheets without any trouble. The depth comes from a pocket spring support system topped with polyester fibre comfort fillings, all under a breathable Belgian damask cover.
What sizes does the Spring King Pocket Backcare 1500 come in?
Three sizes: UK Single, UK Double and UK King, priced from £189 to £299 depending on the size you choose.
Does the Spring King Pocket Backcare 1500 have a guarantee?
Yes, it comes with a 1 year guarantee. That's shorter than many brands offer, which is worth weighing up, though the low starting price of £189 softens the trade-off.
Is the Spring King Pocket Backcare 1500 good for allergies?
It's certified hypoallergenic, so it's a sensible pick if dust or allergens tend to disturb your sleep. It also meets the BS7177: 2008 fire resistance standard for domestic use.
