Assessed from the specification published by Mattress Man, captured September 2026, and from regular price comparison across our UK retail partners.
Price is the strongest argument here. From £249.00, this sits at the affordable end for a memory foam mattress from a major brand, and the range topping out at £439 keeps even larger sizes within reach. Across 215 verified ratings on mattressman.co.uk, it holds an average of 4.6 out of 5, which suggests most owners are happy with what arrives. If you buy through Mattressman, that retailer lists free next day delivery and a 60-night trial, so you can sleep on it at home before committing fully. Do note those terms are Mattressman's own offer rather than Silentnight's, so check the details wherever you choose to buy.

Who's it NOT for?
If you want full transparency on foam depths, firmness rating or certifications, the available product information doesn't provide them, which may frustrate a detail-focused buyer. And if you prefer the springy, on-top-of-the-bed feel of a pocket sprung mattress, an all-foam design like this probably isn't for you.
Silentnight Memory 3 Sleep Mattress
View all mattresses
How much does the Silentnight Memory 3 Sleep Mattress cost?
Prices range from £249 to £439 depending on the size you choose, starting from £249.00. That places it at the budget-friendly end for a branded memory foam mattress, though the exact price will depend on which size and retailer you buy from.
What sizes does the Silentnight Memory 3 come in?
Seven sizes are available: UK Single, UK Double, UK King and UK Super King, plus EU Single, EU Double and EU King. The EU options are useful if you have a continental-sized bed frame, which many UK retailers don't cater for.
Does the Silentnight Memory 3 come with a sleep trial?
Mattressman lists a 60-night trial with this mattress. That trial is Mattressman's own offer rather than a Silentnight guarantee, so if you buy elsewhere the terms may differ. Always confirm the trial and returns policy with your chosen retailer before ordering.
Is delivery free on the Silentnight Memory 3 mattress?
Mattressman offers free next day delivery on this mattress. As with the trial, that's the retailer's own service rather than a manufacturer promise, so delivery speed and cost could vary if you purchase from a different shop.
Is the Silentnight Memory 3 any good?
Across 215 owner ratings on mattressman.co.uk, it averages 4.6 out of 5, which is a strong score for a mattress at this price. Detailed written feedback is limited, though, so treat the number as a broad signal rather than a full picture.
