Above the Spring King Madrid 1000 Pocket's springs, soft polyester fibre fillings and a breathable Belgian damask cover keep things simple. At 25cm deep, it has a bit more substance than many budget mattresses. It suits sleepers who want dependable, traditional support without paying for memory foam or hybrid extras. If you want deep pressure-relieving comfort layers, though, this basic build may feel a little firm underneath you.

Why should you choose this mattress?
Choose the Madrid 1000 if you want pocket spring support at a low price. The independent springs adjust to your shape and reduce the roll-together you get with cheaper open coil designs, which means less disturbance if you share the bed. It's National Bed Federation approved, hypoallergenic and meets the BS7177: 2008 fire safety standard for domestic use, reassuring credentials at an affordable starting price. Six sizes are available, from UK Small Single up to UK Super King, and delivery is free next day to mainland UK, although some addresses may incur a small fee. Yes, the fillings are simple polyester fibre rather than anything plush, but that keeps the cost down.
Key features & layer details
Cover
A breathable Belgian damask fabric cover, which means air can move through the sleep surface rather than trapping warmth against you. It's a traditional, hard-wearing choice.
Comfort Fillings
Soft white fibre fillings made from 100% polyester. These give a gentle cushioned feel over the springs, though they're simpler than the foam layers found on pricier mattresses.
Support System
1,000 individually pocketed springs, each mounted in its own separate fabric pocket so they work completely independently of one another. In practice, that means support follows your body's contours and your partner's movements are less noticeable.

Best suited for?
Couples
Individually pocketed springs work independently of one another, which means your partner's movements are less noticeable and there is less roll-together than on cheaper open coil designs.
Budget buyers
Pocket spring support with a 25cm depth and simple polyester fillings keeps the cost down, so it is described as an affordable way to get a sturdier build.
Allergy sufferers
The mattress is hypoallergenic and has a breathable Belgian damask cover, which suits anyone who wants a straightforward, simple sleep surface.
Warm sleepers
A breathable damask cover lets air move through the sleep surface, which means less warmth gets trapped against you overnight.
Guest rooms
Six sizes from UK Small Single to Super King, plus fire safety approval for domestic use, make it an easy fit for a spare bedroom.
If you love a deep, cradling feel, the slim polyester fillings here won't give you that, and side sleepers with sensitive hips may want something softer than medium firm. It's also less suited to anyone wanting a long guarantee, as Spring King offers one year on this model.
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
How firm is the Spring King Madrid 1000 mattress?
Spring King describes it as medium firm. That suits most back and front sleepers, although lightweight side sleepers may find it a little too firm through the shoulders and hips.
How many springs does the Madrid 1000 have?
It contains 1,000 individually pocketed springs, each in its own separate fabric pocket. They work independently of one another, so support adapts to your shape and movement transfers less across the bed.
How deep is the Spring King Madrid 1000?
It's 25cm deep, which is a reasonable depth for a pocket spring mattress at an affordable starting price and should fit standard fitted sheets comfortably.
What guarantee comes with the Spring King Madrid 1000?
It comes with a 1 year guarantee, which is shorter than many brands offer. The mattress is National Bed Federation approved, which gives some added reassurance about how it's made.
Is the Spring King Madrid 1000 good for allergy sufferers?
It's listed as hypoallergenic, and the fillings are 100% polyester fibre rather than natural materials, which some allergy sufferers prefer. It also meets the BS7177: 2008 fire safety standard for domestic use.
