The Relyon Wallbridge Ortho 2500 is built around 2500 pocket springs, which means each spring moves independently to follow your shape rather than pushing back as one flat surface. Above the springs sit Somerset wool, cotton and soft white polyester fibres, so it sleeps cooler than most foam-heavy designs. At 29cm deep, it's a substantial mattress from an NBF-Approved manufacturer, delivered flat rather than rolled and boxed. If you sleep hot or want proper firm support with natural materials, it's a strong candidate, although the firm feel won't suit everyone.

Why should you choose this mattress?
The main appeal here is genuine firm support paired with breathable natural fillings. Sustainably sourced Somerset wool regulates temperature, which means fewer sweaty nights if you tend to overheat, and the cotton layer adds natural comfort alongside it. The 2500 pocket springs include additional mini springs for closer support, so pressure relief should feel more precise than a basic sprung mattress. It carries a Relyon 10-year guarantee as stated on the MattressNextDay listing, plus hypoallergenic credentials and fire resistance certified to BS7177: 2008. Yes, it's a firm mattress and not a plush one, but if firm is what your back needs, the wool and cotton stop it feeling harsh on the surface.
Key features & layer details
Belgian Damask Viscose Sleep Surface
A silky, breathable cover that helps keep the sleep surface feeling fresh. It's the first thing you'll feel, and it's noticeably softer than the firm rating might suggest.
Sustainably Sourced Somerset Wool
Wool is naturally breathable and gently cushioning, which means it helps regulate your temperature through the night. It also gives the firm build a touch of resilient comfort at the surface.
Soft White Fibres
These fibres are made from 100% polyester, chosen for recovery and durability. In practice, that means the comfort layers should hold their shape rather than flattening quickly.
Cotton
A natural filling that helps regulate body temperature and adds a layer of support. Combined with the wool above it, this keeps the mattress breathable throughout.
2500 Pocket Springs
Each spring sits in its own fabric pocket and works independently, which means better pressure relief and less motion transfer than an open coil unit. Additional mini pocket springs provide closer, more responsive support.

Best suited for?
Warm sleepers
Somerset wool and cotton fillings are naturally breathable and help regulate temperature, so it sleeps cooler than most foam-heavy designs if you tend to overheat.
Back sleepers
Firm support from 2500 pocket springs, with extra mini springs for closer response, keeps the body level while the wool and cotton stop the surface feeling harsh.
Couples
Each pocket spring works independently, which means less motion transfer than an open coil unit, so one person's movement is less likely to disturb the other.
Allergy sufferers
Hypoallergenic credentials and natural wool and cotton fillings make this a sensible choice if you want bedding materials that suit sensitive sleepers.
Eco-conscious buyers
Sustainably sourced Somerset wool and natural cotton make up the comfort layers, giving you a mattress built around natural materials rather than foam.
This is a firm mattress, so lightweight side sleepers may find it a little too unyielding on the shoulders and hips. It's delivered flat rather than rolled, which makes it heavier to manoeuvre up narrow stairs. And if you want a memory foam hug, the springy, natural-filled feel here is quite different.
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 Relyon Wallbridge Ortho 2500 firm or soft?
It's rated firm. The wool, cotton and polyester fibre layers soften the surface slightly, but the underlying support is properly firm, which suits back sleepers and anyone who finds softer mattresses leave them sinking too far.
Does the Relyon Wallbridge Ortho 2500 come with a guarantee?
The MattressNextDay listing states a Relyon 10 Year Guarantee. No trial period is stated on that page, so check the returns terms with whichever retailer you buy from before ordering.
Is the Relyon Wallbridge Ortho 2500 good for hot sleepers?
It should be. The Somerset wool and cotton fillings are naturally breathable and help regulate temperature, and the viscose cover is designed for a fresher sleeping environment. Sprung, natural-filled mattresses like this generally sleep cooler than foam-dominant designs.
What sizes does the Relyon Wallbridge Ortho 2500 come in?
It's available in UK Single, Double, King and Super King.
Is the Relyon Wallbridge Ortho 2500 delivered rolled up?
No, it arrives flat rather than rolled and boxed, which is normal for a traditionally built pocket sprung mattress. MattressNextDay lists free next-day delivery as a retailer offer, so delivery terms may differ elsewhere.
