Assessed from mattress data provided by our UK retail partners, captured September 2026, and from regular price comparison across those retailers.
Extra firm mattresses suit people who sleep on their back or front and want a surface that holds them level rather than letting them sink. This one is a hybrid, so you get the responsive support of springs alongside foam comfort layers, rather than the slower, more enveloping feel of an all-foam design. The 25cm depth is a solid build for the money, and at £599 for a Super King it sits at the more affordable end for that size. We found it listed at just one retailer, so it's not the easiest mattress to shop around for, but the price itself is honest for a large hybrid.
Key Features & what's inside
Awaiting up to date specifications. Please check back later.
Who's it NOT for?
Lightweight sleepers and dedicated side sleepers may find extra firm too unforgiving on shoulders and hips. It's also no use if you need any size other than a UK Super King, as that's the only option listed. If you prefer a softer, hugging feel, look at a medium hybrid or all-foam design instead.
Mlily Hybrid Gel 2000 Ortho Mattress
How firm is the Mlily Hybrid Gel 2000 Ortho mattress?
It's listed as Extra Firm, the firmest end of the scale. That suits back and front sleepers who want a flat, supportive surface, although lightweight side sleepers may find it too hard around the shoulders and hips.
What sizes does the Mlily Hybrid Gel 2000 Ortho come in?
It's listed in one size only: UK Super King. If you need a smaller size, you'll want to look elsewhere in Mlily's range or at another brand.
How much does the Mlily Hybrid Gel 2000 Ortho cost?
It's priced at £599 for the UK Super King, which is reasonable for a 25cm hybrid in the largest standard UK size.
How deep is the Mlily Hybrid Gel 2000 Ortho mattress?
It's 25cm deep. Standard fitted sheets for a deep mattress should work fine, though it's worth checking your bedding before it arrives.
