Assessed from Silentnight's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
This is a sensible choice if you want memory foam comfort without the fully-foam feel, since the 1000 pocket springs distribute weight evenly and make moving around in bed easier. The memory foam layer moulds to your body for pressure relief at the hips and shoulders. It's hypoallergenic and dust mite resistant, which matters if you're prone to allergies. The Medium/Firm feel gives a supportive, slightly firmer surface that most sleepers get on with. Yes, the £289 to £499 price range signals a no-frills build, but you still get a 60-night trial and a 5-year guarantee, so there's little risk in trying it. Five UK sizes are available, from Single up to Super King.

Who's it NOT for?
If you sleep hot, memory foam can hold warmth, so a breathable spring-only or natural-fibre mattress may suit you better. Lightweight side sleepers may find the Medium/Firm feel slightly too firm at the shoulder. And if you want a plush, deeply layered premium hybrid, this simpler build won't be it.

Is the Silentnight Comfort Pocket Essentials mattress firm or soft?
Silentnight rates it Medium/Firm. That means a supportive surface with a slightly firmer feel, which suits back and stomach sleepers well. Lightweight side sleepers may find it a little too firm for full pressure relief at the shoulder.
How many springs does the Silentnight Comfort Pocket Essentials have?
It contains 1000 Mirapocket springs in a single support unit. Each spring moves independently, which means even weight distribution, easier movement in bed and better spinal alignment through the night.
Does the Silentnight Comfort Pocket Essentials come with a trial?
Yes. Silentnight offers a 60-night trial on this mattress, alongside a 5-year guarantee, so you have a couple of months to decide whether the Medium/Firm feel suits you. Delivery is listed at 14 days.
Is the Silentnight Comfort Pocket Essentials good for allergies?
It's listed as hypoallergenic and dust mite resistant, which makes it a reasonable choice if allergies disturb your sleep. The sleep surface is 100% polyester rather than natural fibres, which some allergy sufferers prefer.
What sizes does the Silentnight Comfort Pocket Essentials come in?
Five UK sizes: Single, Small Double, Double, King and Super King. Prices range from £289 to £499 depending on the size, and the mattress is 25cm deep across the range.
