Assessed from mattress data provided by our UK retail partners, captured September 2026, and from regular price comparison across those retailers.
If you sleep on your side, or simply prefer a bed that lets you sink in a little, the soft feel here is the main draw. Soft mattresses tend to cushion shoulders and hips more readily, which side sleepers usually appreciate. The £348 price for a UK King is honest value from a familiar brand, and the eco-friendly billing may appeal if sustainability matters to you. The retailer listing includes a 5 year guarantee, which gives some reassurance at this price. It won't suit everyone, and back or front sleepers who need firmer support should think carefully before choosing a soft model.

Who's it NOT for?
If you sleep on your back or front, or you're a heavier sleeper, a soft mattress may not give you the support you need and could leave you feeling you've sunk too far in. It's also only available in UK King, so anyone needing a single, double or super king is out of luck here.
Silentnight Moretto Miracoil Mattress
View all mattresses
How firm is the silentnight moretto miracoil mattress?
It's catalogued as soft. That means a gentler, more cushioning feel, which tends to suit side sleepers and lighter bodies. If you prefer a firmer, more supportive surface, particularly as a back or front sleeper, this probably isn't the right pick.
What sizes does the silentnight moretto miracoil come in?
We currently see it listed in one size only, UK King, from a single retailer. If you need a different size, you'll need to look at other models in the Silentnight range or elsewhere.
Does the silentnight moretto miracoil have a guarantee?
The retailer listing states a 5 year guarantee. As that comes from a retailer's listing rather than Silentnight's own page, it's worth confirming the terms with the seller before you buy.
How much does the silentnight moretto miracoil cost?
It's priced at £348 for the UK King size. That's a reasonably accessible price for a branded king-size mattress, though it's the only size and price point we currently see listed.
