Assessed from the specification published by MattressNextDay, captured September 2026, and from regular price comparison across our UK retail partners.
The appeal here is natural materials at a reachable price. Wool is naturally temperature-regulating, which means it helps you stay warmer in winter and cooler in summer, and the silk layer adds a soft, light-touch surface feel. Underneath, 1,000 pocket springs move independently of one another, so you feel supported at your hips and shoulders without the whole bed dipping when a partner turns over. The medium feel suits most back and side sleepers, although heavier sleepers who prefer a firmer surface may want more resistance. Relyon backs it with a 10-year guarantee, as listed on the MattressNextDay page, and the brand is an NBF-approved manufacturer, which gives some reassurance about build quality. Five UK sizes are available, from single to super king.
Key Features & what's inside
- Belgian Damask Viscose Sleep Surface. A silky, breathable damask cover, which means air can move through the sleep surface more easily. That helps the bed feel a little fresher through the night.
- Silk. A light, soft silk layer sits near the top of the mattress. It adds a gentle, luxurious feel without trapping heat.
- Sustainably Sourced British Wool. Wool gives cushioning with natural resilience, which means it springs back rather than compressing flat over time. It also regulates temperature well, a plus if you run warm.
- Deep soft layer. A deeper soft layer adds extra cushioning between the natural fibres and the springs. It softens the initial feel when you lie down.
- 1000 Pocket Springs. Each spring sits in its own fabric pocket and moves independently, which means the mattress responds to your shape rather than pushing back as one unit. That gives better pressure relief and less motion transfer between partners.

Who's it NOT for?
If you like a properly firm mattress, the medium feel here may be softer than you'd want, particularly if you're a heavier sleeper. Equally, if you're after the slow, contouring hug of memory foam, this traditional sprung build won't give you that. And no trial period is mentioned on the listing, which cautious buyers should weigh up.
Relyon Guildford 1000 Mattress

How firm is the Relyon Guildford 1000 mattress?
The product page describes it as medium, so expect a balanced feel with some cushioning from the wool, silk and soft comfort layers. It suits most back and side sleepers, although lightweight side sleepers may find any sprung mattress a touch firmer than a foam one, and heavier sleepers may prefer something firmer.
What is the Relyon Guildford 1000 made of?
It combines a Belgian damask viscose cover, a silk layer, sustainably sourced British wool and a deep soft comfort layer over 1,000 individual pocket springs. The natural fibres help with breathability and temperature regulation, while the pocket springs provide independent, pressure-relieving support. The mattress is 25cm deep.
Does the Relyon Guildford 1000 come with a guarantee?
Yes. The MattressNextDay listing states it comes with a Relyon 10-year guarantee, which is a reasonable span for a mattress at this price. No sleep trial is mentioned on that page, so check returns terms with your chosen retailer before you buy.
What sizes does the Relyon Guildford 1000 come in?
Five UK sizes: single, small double, double, king and super king. Prices range from £319 to £599 depending on the size you choose, starting from £319 for the smallest option.
Is the Relyon Guildford 1000 good for hot sleepers?
It should cope reasonably well. The breathable viscose cover and British wool layer both help air move and regulate temperature, and sprung mattresses generally sleep cooler than all-foam designs. If overheating is your main concern, this natural-fibre build is a sensible direction.
