Assessed from Silentnight's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
The main draw here is honest value. Prices run from £239 to £349 across UK Single, Double and King, and Silentnight backs it with a 60-night trial and a 5-year guarantee on its own site. The Mirapocket unit's 600 zoned springs give even weight distribution and support spinal alignment, which means fewer aches from a sagging middle. Being double sided, you can turn it regularly to extend its life, a chore, but a worthwhile one. It's hypoallergenic and dust mite resistant, so allergy sufferers get some reassurance too. Yes, 600 springs is a modest count, but for a spare room or a first flat it does the job without fuss.

Who's it NOT for?
If you want a plush, deep-cushioned feel, this medium mattress with a fairly simple fibre comfort layer will feel a little basic. Anyone unable or unwilling to flip a mattress regularly loses the main benefit of its double-sided design. Heavier sleepers wanting a high spring count for extra support may want to look further up the range.
Silentnight Essentials Pocket 600 Double Sided Mattress
View all mattresses
Is the Silentnight Essentials Pocket 600 double sided?
Yes. Silentnight describes it as double sided, meaning you should rotate and turn it regularly. Both sides have the same stitched sleep surface, and sharing the wear between them tends to help the mattress last longer.
How firm is the Silentnight Essentials Pocket 600?
Silentnight rates it as medium. That suits most sleepers, giving a balance of cushioning and support from the 600 zoned Mirapocket springs, although anyone who prefers a distinctly firm or soft feel may want a different tension.
Does the Silentnight Essentials Pocket 600 come with a trial?
Bought from Silentnight's own site, it comes with a 60-night trial and a 5-year guarantee. If you buy through another retailer, check their terms, as trial and returns policies can differ.
Is the Silentnight Essentials Pocket 600 good for allergies?
It should be a reasonable choice. It's Allergy UK approved, hypoallergenic and dust mite resistant, which means the materials are designed to limit the common triggers that disturb allergy-prone sleepers.
How deep is the Silentnight Essentials Pocket 600?
It's 26cm deep, and that depth is consistent across all sizes: UK Single, Double and King. Standard fitted sheets should fit without any trouble.
