The Relyon Comfort Pure Memory 1400's foam wraps around your shape for pressure relief, which means you get that gentle sink-in feel, while the springs underneath keep you properly supported and move independently, so a restless partner is less likely to wake you. It's handcrafted in the UK and approved by the National Bed Federation. The price feels fair for a pocket sprung hybrid at this depth. Sizes are limited, though: UK Single, Small Double and Super King only.

Why should you choose this mattress?
This mattress suits sleepers who want memory foam comfort without the fully enclosed, sometimes warm feel of an all-foam bed. The knitted cover is designed to enhance airflow, and the sprung core lets air circulate more freely than solid foam. The medium to firm feel works well for back and combination sleepers, although lightweight side sleepers may find it slightly too firm. If you buy through Mattress Online, the retailer lists a 100-night trial, a 10-year guarantee and free next day weekday delivery, with old mattress removal available for an extra charge. Across owner reviews it holds a 4.7 rating, from a modest number of reviewers, but the feedback is consistently positive.
Key features & layer details
Knitted cover
A soft knitted finish that adds a touch of cosiness, which means the surface feels inviting rather than clinical. Knitted covers are breathable and help air move through the sleep surface.
Memory Foam
A 5cm layer of memory foam that moulds to your shape, which means pressure is lifted from your hips and shoulders as you settle in. Expect a gentle sink-in feel rather than sleeping on top of the mattress.
Soft White Fibres
A dense layer of soft synthetic fillings that adds cosy comfort while reinforcing the medium to firm feel. It also works as an insulator pad, protecting you from feeling the spring unit beneath.
Pocket Springs
A core of 1400 pocket springs, each in its own fabric pocket, adapts to your movement through the night. Because the springs move independently, you and a partner are less likely to disturb each other.

Best suited for?
Back sleepers
The medium firm feel and 1400 pocket springs give steady support under the hips, while the memory foam layer still softens the surface.
Combination sleepers
Medium to firm tension and a sprung core make shifting between positions easier, so you are not sinking into the foam each time you turn.
Couples
Each of the 1400 pocket springs sits in its own fabric pocket and moves independently, so a restless partner is less likely to wake you.
Warm sleepers
A knitted cover designed to enhance airflow and a sprung core that lets air circulate more freely than solid foam help the bed feel less enclosed.
If you like a soft, cradling mattress, the medium to firm feel here will probably be firmer than you want, particularly if you're a lightweight side sleeper. Anyone needing a UK Double or King is out of luck too, as sizes are limited to Single, Small Double and Super King.
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 Comfort Pure Memory 1400 firm or soft?
It's described as medium to firm. The 5cm memory foam layer gives a sink-in feel on the surface, but the densely packed fibres and pocket spring core keep the overall support on the firmer side. Most back and combination sleepers should find it comfortable, although lighter side sleepers may want something softer.
Does the Relyon Comfort Pure Memory 1400 come with a trial?
Mattress Online lists a 100-night trial with this mattress. That trial is the retailer's own offer rather than a Relyon guarantee, so if you buy elsewhere, check that retailer's returns terms before ordering.
How deep is the Relyon Comfort Pure Memory 1400 mattress?
It's 30cm deep, which is a generous depth. Yes, that means standard fitted sheets can be a snug fit, but the extra height reflects the layered build of foam, fibres and a full pocket spring unit.
What guarantee does the Relyon Comfort Pure Memory 1400 have?
The mattressonline.co.uk listing states a 10-year guarantee. As this appears on a retailer listing rather than Relyon's own page, it's sensible to confirm the guarantee terms with whichever retailer you buy from.
Does the Relyon Comfort Pure Memory 1400 sleep hot?
It should run cooler than an all-foam mattress. The knitted cover is breathable and designed to enhance airflow, and the pocket spring core allows air to circulate through the mattress. That said, memory foam does hold some warmth, so very hot sleepers may prefer a foam-free build.
