If you sleep on your side, or you simply prefer sinking into your mattress rather than lying on top of it, the medium soft feel here is the main draw. Softer hybrids are a little harder to find than medium or medium firm ones, so this fills a genuine gap. The 29cm depth suggests a generously built mattress, and the four sizes on offer cover most UK bed frames. Starting at £849 it sits at the pricier end for many budgets, though deep hybrid mattresses do tend to cost more than simpler foam designs. It's currently stocked by one retailer, so shopping around for a better price isn't really an option.
Key Features & what's inside

Who's it NOT for?
A medium soft mattress is unlikely to suit dedicated front sleepers or heavier bodies, who generally need firmer support to keep the spine aligned. If you like a solid, supportive surface with minimal sink, this probably isn't the one for you. Budget shoppers may also baulk at the £849 starting price.

How firm is the Emma Diamond Spring Free Deluxe mattress?
It's listed as medium soft, which means a gentler, more forgiving feel than the medium or medium firm rating most mattresses carry. That tends to suit side sleepers and lighter bodies best, as it allows the shoulders and hips to sink in slightly. Front sleepers and heavier people usually do better with something firmer.
How deep is the Emma Diamond Spring Free Deluxe mattress?
It measures 29cm deep, which is a generous depth for a hybrid mattress. Just check your fitted sheets before it arrives, as some standard sheets struggle with mattresses this deep and you may need deep-fitted ones.
What sizes does the Emma Diamond Spring Free Deluxe come in?
Four UK sizes are available: Single, Double, King and Super King. Prices range from £849 to £1,199 depending on which size you choose. There's no small double or European sizing listed, so if you need either of those you'll want to look elsewhere.
How much does the Emma Diamond Spring Free Deluxe cost?
Prices start at £849 and go up to £1,199, depending on size. That places it at the premium end of the market, which is fairly common for deep hybrid designs. It's stocked by one retailer at present, so there's little scope to compare prices across shops.
