Assessed from the specification published by Mattress Man, captured September 2026, and from regular price comparison across our UK retail partners.
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. At £345 for a Single, 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.

Who's it NOT for?
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.

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. Prices range from £345 to £649 depending on the size you choose.
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.
