Silentnight 1000 Pocket Ortho Mattress
The Silentnight 1000 Pocket Ortho is a pocket spring mattress from one of the UK's biggest sleep brands.
- Firm feel for back sleepers
- Springs move independently
- Hypoallergenic knitted cover
The Silentnight 1000 Pocket Ortho uses 1,000 Mirapocket springs, which means each spring moves independently, so you get support shaped to your body rather than a single tensioned surface. Fibre fillings sit over the springs for comfort. The 'Ortho' name usually signals a firmer, more supportive feel, though we couldn't confirm an official firmness rating for this model, so treat that as a pointer rather than a promise. It comes in five sizes, from UK Single up to UK Super King.

Why should you choose this mattress?
This is a sensible choice if you want pocket sprung support at a modest price. The 1,000 Mirapocket springs respond to each sleeper separately, which means you're less likely to feel a partner shifting about in the night. Fibre fillings keep the comfort layer simple and tend to sleep cooler than deep foam, a small win if you run warm. It sits at the affordable end for a branded pocket spring mattress, and the trade-off is a fairly straightforward specification rather than layers of speciality foam. Buying through Mattressman gets you free next day delivery and a 60-night trial, though those are that retailer's own terms, not Silentnight's.
Key features & layer details
Soft knit cover
A soft knitted cover with a hypoallergenic finish. It adds a little comfort at the surface and suits you if you want a cover that's gentler on sensitive sleepers.
Eco Comfort fibre filling
Eco Comfort Fibre filling layers sit under the cover and give gentle cushioning. It's a simple, fairly light comfort layer, so expect less sink-in than you'd get from deep foam.
Mirapocket spring core
1,000 individual Mirapocket springs, each working independently to spread weight evenly. This means support follows your shape, and you're less likely to feel a partner move.

Best suited for?
Couples
The 1,000 Mirapocket springs respond to each sleeper separately, which means you are less likely to feel your partner shifting about in the night.
Warm sleepers
Fibre fillings over the springs tend to sleep cooler than deep foam, which helps if you often get too hot overnight.
Budget buyers
Sitting at the affordable end for a branded pocket spring mattress, it gives you independent spring support without paying for layers of speciality foam.
Back sleepers
The ortho-style feel usually points to a firmer, more supportive surface, which suits lying flat, though no official firmness rating could be confirmed.
If you like a soft, cushioned, sink-in feel, an ortho-style mattress is unlikely to suit you. Side sleepers with prominent pressure points may also find the simple fibre comfort layer a little lean compared with models topped with memory foam or a pillow top.
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 many springs does the Silentnight 1000 Pocket Ortho have?
It contains 1,000 Mirapocket springs. These are Silentnight's pocket springs, each sewn into its own fabric pocket so it compresses independently, which means better contouring to your shape and less motion transfer between partners than an open coil design.
Is the Silentnight 1000 Pocket Ortho firm?
No official firmness rating is listed for this model. The 'Ortho' label typically points to a firmer, more supportive feel, but without a stated rating we'd suggest checking with the retailer before you buy, particularly if you're a lightweight side sleeper who prefers a softer surface.
What sizes does the Silentnight 1000 Pocket Ortho come in?
Five sizes are available: UK Single, UK Small Double, UK Double, UK King and UK Super King.
Does the Silentnight 1000 Pocket Ortho come with a trial?
Mattressman lists a 60-night trial and free next day delivery. These are Mattressman's own offers rather than Silentnight's, so if you buy elsewhere, check that retailer's trial and delivery terms before ordering.
