Inside the Silentnight Eco Comfort Airmesh 3000 Boxtop sit 2000 Mirapocket springs plus 1000 mini pocket springs, which means support that adjusts to your shape rather than pushing back uniformly. A Coolmax cover wicks moisture and a 3D honeycomb Airmesh layer keeps air moving, helpful if you tend to sleep warm. The comfort fillings are made from recycled materials, and Silentnight is a B-Corp certified sleep brand, so there's a genuine sustainability angle here rather than a marketing one. It comes in four UK sizes, and it's mid-range money for a handcrafted, National Bed Federation approved build.

Why should you choose this mattress?
This mattress suits sleepers who want a plush, cushioned surface without giving up proper spinal support. The Eco Comfort Fibre and micro-quilted layers give a soft, quilted feel on top, while the pocket spring core does the structural work underneath, so side sleepers in particular should find pressure relief at the shoulders and hips. Hot sleepers get two cooling features working together: the moisture-wicking Coolmax cover and the Airmesh airflow layer. It's hypoallergenic and handcrafted in the UK, with a 5 year guarantee. If you buy through Mattress Online, they list a 100-night trial and free delivery to most mainland UK locations, though those are the retailer's terms rather than Silentnight's own.
Key features & layer details
Coolmax Cover
A soft-touch Coolmax cover wicks moisture away from your body, which means less clamminess on warmer nights. It's the first line of temperature control before you reach the fillings.
Microquilted Layer
The cover fabric is stitched directly into the filling beneath it, giving that plush, quilted surface feel. You'll notice it as a smooth, slightly pillowy first impression when you lie down.
Eco Comfort Fibre
A finely packed layer of fibres made from recycled materials adds extra padding that cradles your body. It's where much of the mattress's soft, cushioned character comes from.
Airmesh
Silentnight's 3D honeycomb Airmesh uses an open structure to let air move through the mattress. In practice, that means heat has somewhere to go rather than building up around you.
Mirapocket Springs
The core holds 2000 Mirapocket springs alongside 1000 mini pocket springs, all made from durable steel. The mini springs target smaller, harder-to-reach areas like the lower back, so support feels more tailored than a single-spring system.

Best suited for?
Side sleepers
The soft, quilted top with Eco Comfort Fibre padding over a pocket spring core gives cushioning at the shoulders and hips, where side sleepers need it.
Warm sleepers
A moisture-wicking Coolmax cover and an open 3D honeycomb Airmesh layer work together, so heat has somewhere to go instead of building up around you.
Eco-conscious buyers
The comfort fillings are made from recycled materials and Silentnight is a B-Corp certified sleep brand, so the sustainability angle is genuine.
Allergy sufferers
The copy describes this mattress as hypoallergenic, which makes it a sensible pick if you want a bed that avoids common irritants.
Combination sleepers
Having 2000 Mirapocket springs plus 1000 mini pocket springs means support adjusts to your shape, so it follows you as you move between positions.
If you prefer a firm, supportive-feeling surface, this is on the softer side of medium, and the plush boxtop may feel too forgiving. Heavier sleepers who need a firmer platform, and strict back sleepers who like minimal sinkage, may be better served elsewhere. At 35cm deep, check your fitted sheets will cope.
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
How firm is the Silentnight Eco Comfort Airmesh 3000 Boxtop?
The product page lists it as medium. With the plush quilted boxtop and Eco Comfort Fibre padding, it leans towards the softer, more cushioned end of medium, which suits side sleepers and anyone who likes a gentler surface feel.
How many springs does the Eco Comfort Airmesh 3000 have?
It contains 3000 springs in total: 2000 full-size Mirapocket springs and 1000 mini pocket springs. The mini springs sit where finer support is needed, targeting delicate areas for a more personalised feel.
Is the Silentnight Eco Comfort Airmesh 3000 good for hot sleepers?
It has two features aimed at temperature. The Coolmax cover wicks moisture away to reduce humidity, and the 3D honeycomb Airmesh layer allows greater airflow through the mattress, so it's a reasonable pick if you tend to overheat at night.
Does the Silentnight Eco Comfort Airmesh 3000 come with a trial?
Mattress Online lists a 100-night trial on this mattress, but that's the retailer's own offer rather than a Silentnight guarantee, so check the terms wherever you choose to buy. The mattress itself carries a 5 year guarantee.
What sizes does the Silentnight Eco Comfort Airmesh 3000 come in?
It's available in UK Single, Double, King and Super King. The mattress is 35cm deep, so it's worth checking your fitted sheets accommodate a deeper profile.
