In the Silentnight Comfortable Foam Mattress, the soft foam tends to let you sink in a little rather than lying on top of the surface, which usually suits side sleepers and lighter bodies best. It comes in seven sizes, including EU sizes alongside the standard UK ones, which is handy if you have a continental bed frame.

Why should you choose this mattress?
If you sleep on your side and like a gentle, cushioned feel, a soft foam mattress like this one is a sensible place to start. Foam also absorbs movement well, which means you're less likely to feel a partner shifting about during the night. The price is modest too: this sits at the budget end of the market, so it could suit a spare room, a first flat or a child moving up to a bigger bed. The EU sizing options are genuinely uncommon among UK brands, and worth a look if a standard UK mattress has never quite fitted your frame.
Key features & layer details
We’re still collecting information on this mattress. Unfortunately, we don’t have its key features yet.
Best suited for?
Side sleepers
The soft foam lets your shoulder and hip sink in a little rather than sitting on top, giving a gentle, cushioned feel.
Lighter sleepers
Lighter bodies tend to sink into the soft foam just enough to feel cushioned, which is where this firmness works best.
Couples
Foam absorbs movement well, which means you are less likely to feel your partner shifting about during the night.
European bed frames
Seven sizes include EU options alongside standard UK ones, so a continental frame can get a mattress that fits it properly.
Budget buyers
Sitting at the budget end of the market, it suits a spare room, a first flat or a child moving up.
This is a soft mattress, so it's unlikely to suit front sleepers or heavier bodies, who generally need a firmer surface to keep the spine level. If you find foam mattresses warm, or you prefer the springy, supported feel of pocket springs, this simple all-foam design probably isn't for you.
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 Comfortable Foam Mattress soft or firm?
It's listed as soft. That means you'll sink into the surface a little rather than resting on top of it, a feel that tends to suit side sleepers and lighter people. If you sleep on your front, or simply prefer a firmer feel, this probably isn't the right pick.
What sizes does the Silentnight Comfortable Foam Mattress come in?
Seven sizes are listed: UK Single, UK Small Double, UK Double and UK King, plus EU Single, EU Double and EU King. The EU options are useful if you own a continental bed frame, as standard UK mattresses often leave a gap or overhang on those.
How much does the Silentnight Comfortable Foam Mattress cost?
It depends on the size you choose, and the price table on this page shows the current price for each size. It sits firmly at the budget end of the market, which makes it a reasonable option for a spare room or a first mattress.
