Temperature regulation is the headline here. The Coolmax surface and 3D honeycomb Airmesh layer work together to keep air moving through the mattress, so hot sleepers should notice a fresher feel than a standard quilted mattress gives. Underneath, zoned Mirapocket springs adapt to different areas of your body, which means your spine stays better aligned and pressure eases at the hips and shoulders. A layer of 1,000 mini pocket springs adds a second stage of comfort and helps reduce motion transfer, useful if you share a bed with a restless partner. The eco credentials are more than a sticker: recycled, recyclable fibres and a B-Corp certified brand. Mattress Online lists a 100-night trial, so you can try it at home first.
Key Features & what's inside
- Coolmax sleep surface. A moisture-wicking sleep surface, which means sweat is drawn away from your body rather than sitting against your skin. The result is a fresher, drier feel through the night.
- Airmesh comfort layer. A 3D honeycomb mesh that uses your movement to push air around the mattress. In practice, this means better circulation and a cooler sleeping environment.
- Eco Comfort Fibre. Soft fibres made from recycled materials, fully recyclable at the end of the mattress's life. They mould around your contours for a plush, pressure-relieving surface feel.
- Mirapocket Springs support system. Silentnight's zoned pocket springs, designed to react to different areas of your body independently. This helps align your spine, which you'll feel as steadier posture support and less pressure build-up.
- Mini Pocket Springs. A layer of 1,000 mini springs sitting within the build for extra comfort and pressure relief. They also cut down motion transfer, so a partner's movement is less likely to wake you.

Who's it NOT for?
If you want a firm, supportive-feeling surface from day one, this medium mattress may feel too forgiving, and owner reviews suggest it needs a settling-in period. It's also a heavy mattress at 31cm deep, so it may not suit anyone who struggles to lift or rotate a mattress, or to change fitted sheets, alone.

How many springs does the Silentnight Eco Comfort Airmesh 1600 have?
It has 1,600 pocket springs in total, combining Silentnight's zoned Mirapocket support springs with a layer of 1,000 mini pocket springs. The two layers work together: the main springs handle support and spinal alignment, while the mini springs add surface comfort and reduce motion transfer.
Is the Silentnight Eco Comfort Airmesh 1600 firm or soft?
It's rated medium, which suits most sleeping positions, although owner reviews mention it can feel a little firm when new and softens with use. Lighter sleepers may find it takes a few weeks to break in fully.
Does the Silentnight Eco Comfort Airmesh 1600 come with a trial?
Mattress Online lists a 100-night trial with this mattress, along with a 5-year guarantee. Bear in mind these are the retailer's own terms rather than Silentnight's, so check the conditions wherever you buy.
Is the Silentnight Eco Comfort Airmesh 1600 good for hot sleepers?
Yes, cooling is its strongest suit. The Coolmax surface wicks moisture away and the 3D honeycomb Airmesh layer circulates air as you move, and owner reviews specifically praise its temperature regulation. If you regularly overheat at night, it's a sensible pick.
How deep is the Silentnight Eco Comfort Airmesh 1600 mattress?
It's 31cm deep, which is on the generous side, so it's worth checking your fitted sheets will stretch to fit. Deeper sheets designed for taller mattresses are the safer bet.
