The Relyon Prairie 1000 pairs 1,000 individual pocket springs with soft white fibres and a dual density polyester pad, which means you get a supportive, stable feel rather than a sinking one. It comes in five UK sizes from Single to Super King. It's a straightforward, traditionally built mattress that suits people who know they want firm support, although if you sleep on your side and are on the lighter side, it may feel a little too solid at the shoulders and hips.

Why should you choose this mattress?
This is a sensible pick if you want firm support without paying a premium for foam layers you don't need. The 1,000 pocket springs are individually encased in cloth pockets, so they respond to each part of your body separately, which means less roll-together if you share the bed. The damask cover doesn't retain heat, a quiet advantage if you sleep warm. It's handcrafted in the UK and conforms to BS7177: 2008 for fire resistance. Mattress Online lists it with free delivery to most locations and a 100-night trial, so you can try it at home before committing. The feel takes adjusting to if you're coming from a softer mattress, but that firmness is the whole point here.
Key features & layer details
Damask cover
A finely woven, durable fabric that's soft to the touch and doesn't retain heat, which means it should stay comfortable on warmer nights. It's built for long-lasting performance rather than a plush pillow-top feel.
Soft White Fibres
Soft synthetic fillings that add a cosy layer over the firmer materials beneath. They're durable and resilient, designed to hold their shape over time rather than flattening quickly.
Dual density polyester pad
Plush on one side and densely packed on the other, this pad reinforces the firm feel of the mattress. In practice it means you get a small amount of surface softness without losing that solid support underneath.
Pocket Springs
1,000 individual springs, each encased in its own cloth pocket, adapt to your movement independently. That means support is distributed to each part of your body, and your partner's movements are less likely to disturb you.

Best suited for?
Back sleepers
The firm feel and 1,000 pocket springs keep the body level and supported, which suits anyone who wants a stable surface rather than a sinking one.
Couples
Each of the 1,000 springs sits in its own cloth pocket and moves independently, which means less disturbance when your partner shifts during the night.
Warm sleepers
The damask cover is finely woven and doesn't retain heat, which should help the surface stay comfortable on warmer nights.
Heavier sleepers
Firm pocket springs and a dense polyester pad underneath give a solid, supportive base that resists sinking in, so the mattress should feel steady under more weight.
Front sleepers
A firm surface with a dual density pad underneath keeps the body from dipping too far, which helps the hips stay in line.
If you prefer a soft or medium feel, this isn't your mattress: it's firm, and owner feedback suggests it takes adjustment if you're used to something softer. Lightweight side sleepers may find it a little too unyielding at the pressure points, and some owners add a topper to soften the surface.
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 Relyon Prairie 1000 Pocket mattress?
It's rated firm. A dual density polyester pad and 1,000 pocket springs give it a solid, supportive feel, softened slightly by a layer of soft white fibres on top. Owners describe it as genuinely firm, so expect proper support rather than a plush, sink-in surface.
Does the Relyon Prairie 1000 come with a trial period?
Mattress Online lists a 100-night trial with this mattress, along with free delivery to most locations. Those are the retailer's own terms rather than Relyon's, so check the conditions wherever you buy.
How long is the guarantee on the Relyon Prairie 1000?
The Mattress Online listing states a 10-year guarantee, which is reassuring on a mattress at a mid-range starting price. As the terms come from a retailer listing, it's sensible to confirm the guarantee details at the point of purchase.
What sizes does the Relyon Prairie 1000 come in?
Five UK sizes: Single, Small Double, Double, King and Super King.
Is the Relyon Prairie 1000 good for people with back pain?
Some owners in verified reviews report reduced joint and back pain, which fits with its firm, supportive build. That said, firm isn't right for everyone with back trouble, and lighter side sleepers in particular may find it too hard without a topper.
