Assessed from the specification published by Mattress Online, captured September 2026, and from regular price comparison across our UK retail partners.
This mattress makes sense if you want straightforward pocket sprung support at a modest price. The medium to firm feel suits back and front sleepers who need their spine kept fairly level, and the two firmer outer rows of springs give edge-to-edge support, which means you can sleep right up to the side without feeling you might roll off. There's no memory foam here, so it sleeps cooler than foam-heavy designs. Mattress Online lists a 100-night trial and an 8 year guarantee with it, which takes some of the risk out of buying unseen, though those terms are the retailer's own rather than Relyon's.
Key Features & what's inside
- Knitted cover. A soft knitted cover with micro-quilting, which keeps the fillings securely in place so the surface stays even. It's finished with Bio-Protect technology and adds a touch of warmth and cosiness.
- Soft White Fibres. Soft synthetic fillings sit beneath the cover to create a cosy feel over the springs. They're designed to be durable and resilient, holding their shape over time.
- Pocket Springs. 1,000 individual Posturepocket springs, each encased in its own cloth pocket, which means they respond to your body independently and reduce movement transferring across the bed. Two firmer outer rows around the edge give edge-to-edge support.

Who's it NOT for?
It's only available in a UK Single, so couples will need to look elsewhere. The medium to firm feel may be a little too solid for lightweight side sleepers, who often need more give at the shoulder and hip. And if you love the hugging feel of memory foam, this traditional sprung build won't give you that.

How firm is the Relyon Comfort Pure 1000 Pocket mattress?
It's described as medium to firm. That's a supportive feel that suits most back and front sleepers, although lightweight side sleepers may find it slightly too firm for comfortable pressure relief at the shoulders and hips.
Does the Relyon Comfort Pure 1000 come with a trial?
Mattress Online lists a 100-night trial with this mattress. That's the retailer's own offer rather than Relyon's, so if you buy elsewhere, check that seller's returns terms before ordering.
What guarantee does the Relyon Comfort Pure 1000 have?
The retailer listing states an 8 year guarantee, which is a reassuring span for a mattress at this price. As it's listed by the retailer rather than confirmed on Relyon's own site, it's sensible to confirm the terms at checkout.
Is the Relyon Comfort Pure 1000 good for hot sleepers?
It should be a reasonable choice. There's no memory foam in the build, just pocket springs and breathable fibre fillings, and some owners in reviews note it feels cooler than memory foam alternatives.
What sizes does the Relyon Comfort Pure 1000 come in?
It's currently available in a UK Single only, priced from £339.95. If you need a double or king, this particular model won't work for you.
