The Silentnight 3 Zone Memory Foam Mattress pairs a soft knitted sleep surface with a layer of body-moulding memory foam, which means you get cushioning at the surface with a noticeably solid feel underneath. It comes from an NBF-approved manufacturer, is made in the UK, and carries a 5-year manufacturer's guarantee from Silentnight. At 18cm it is slimmer than many mattresses, so it sits lower on the bed frame. If you want firm support at a modest price, it is a sensible shortlist option.

Why should you choose this mattress?
Value is the main draw here. From an affordable starting price, you get memory foam that responds to your shape, helping to ease pressure points at the hips and shoulders, and a knitted surface that adds a slightly softer, more breathable first impression. The firm rating suits back and front sleepers, and heavier sleepers who tend to sink too far into softer foams. Certifications add reassurance: fire resistant to the BS7177: 2008 standard, NBF-approved manufacturer, made in the UK, plus a 5-year guarantee from Silentnight. Sizes run from UK Single to Super King, with EU sizes too, which is handy if you have a continental bed frame. It is a straightforward, budget-friendly firm foam mattress rather than a luxury one.
Key features & layer details
Soft Knitted Sleep Surface
A soft, breathable knitted cover that adds a touch of comfort at the surface. It takes a little of the edge off the firm feel beneath.
Memory Foam
Body-moulding memory foam that responds to your shape, which means pressure points at the hips and shoulders get some relief. Expect a contouring, cradled feel rather than bounce.

Best suited for?
Back sleepers
The firm rating keeps the hips from dropping too far, while the memory foam layer cradles your shape for a supported feel.
Front sleepers
A firm feel underneath helps stop your midsection sinking in, and the soft knitted cover keeps the surface comfortable against your body.
Heavier sleepers
Firm support suits those who tend to sink too far into softer foams, with the memory foam still easing pressure at the hips.
Budget buyers
The copy calls it budget-friendly and good value, giving you a firm memory foam mattress made in the UK without luxury costs.
European bed frames
Sizes run from UK Single to Super King, with EU sizes too, so it should fit a continental bed frame.
Lightweight side sleepers may find the firm feel a little unforgiving on the shoulder. If you like the springy, easy-to-move-on feel of pocket springs, all-foam contouring probably isn't for you. And at 18cm deep, it may feel shallow if you're used to a taller, more substantial mattress.
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 Silentnight 3 Zone Memory Foam Mattress firm or soft?
It is rated firm. The knitted sleep surface and memory foam layer soften the initial feel slightly, but the underlying support is solid. That suits back and front sleepers well, although lightweight side sleepers may find it a little too firm.
How deep is the Silentnight 3 Zone Memory Foam Mattress?
It is 18cm deep, which is slimmer than many mattresses. That keeps the price down and makes it easier to handle, but it sits lower on the bed frame and feels less plush than deeper models.
Does the Silentnight 3 Zone Memory Foam Mattress have a guarantee?
Yes, it carries a 5-year manufacturer's guarantee from Silentnight, as stated on the mattressnextday.co.uk listing.
What sizes does the Silentnight 3 Zone Memory Foam Mattress come in?
UK Single, Small Double, Double, King and Super King, plus EU Single, Double and King. The EU options are useful if you have a continental bed frame.
Does the Silentnight 3 Zone Memory Foam Mattress come with a sleep trial?
No trial period is mentioned on the mattressnextday.co.uk listing, so check returns terms with your chosen retailer before buying. MattressNextDay offers free next day delivery to mainland UK, though some addresses may incur a small fee. Delivery terms are that retailer's own offer.
