Assessed from the specification published by Mattress Man, captured September 2026, and from regular price comparison across our UK retail partners.
The main draw here is price. At £159 to £255 it sits at the affordable end of the market, and it still comes with a 5-year manufacturer guarantee, which gives you a reasonable safety net at this level of spend. Being foam rather than sprung, it should feel quieter and more contouring than a traditional coil mattress, although the retailer page doesn't break down the foam layers, so you're taking the feel somewhat on trust. If you buy from Mattressman, their 60-night trial lets you test it at home, and their free next day delivery means you won't wait long, with handling of 0-1 days and transit of 1-3 days.

Who's it NOT for?
If you prefer the springy, responsive feel of a pocket sprung mattress, an all-foam design like this probably isn't for you. It's also a slightly awkward choice if you like to research construction in detail, as no layer breakdown or firmness rating is published, so you can't be sure of the exact feel before it arrives.
Silentnight Comfortable Foam Sleep Mattress
How much does the Silentnight Comfortable Foam Sleep Mattress cost?
Prices range from £159 to £255 depending on the size you choose, starting at £159.00. That places it at the budget-friendly end of Silentnight's range.
What sizes does the Silentnight Comfortable Foam Sleep Mattress come in?
Six sizes are available: UK Single, UK Double, UK King, plus EU Single, EU Double and EU King. The EU options are useful if you have a continental bed frame, which many UK brands don't cater for.
Does the Silentnight Comfortable Foam Sleep Mattress have a trial period?
Mattressman lists a 60-night trial with this mattress. That trial is the retailer's own offer rather than a Silentnight guarantee, so if you buy elsewhere the terms may differ. Check the returns policy wherever you purchase.
What guarantee comes with the Silentnight Comfortable Foam Sleep Mattress?
It comes with a 5-year manufacturer guarantee, as stated on the Mattressman listing. That's a reasonable span for a mattress at this price point.
How quickly is the Silentnight Comfortable Foam Sleep Mattress delivered?
Mattressman offers free next day delivery on this mattress, with handling taking 0-1 days and transit 1-3 days. This is the retailer's delivery service, so timescales will vary if you buy from another shop.
