If you sleep hot but need firm support, this mattress addresses both. The gel-infused quilted surface and M-Luxe Cool Gel Memory Foam draw heat away from your body, which means less of the warm, sinking feel memory foam is known for. Beneath that, 2,800 pocket springs plus a layer of mini pocket springs adjust to your weight and movement, so support stays consistent whether you shift position or share the bed. It's certified hypoallergenic and vegan friendly, and meets the BS7177: 2008 fire safety standard. Priced between £599 and £799 depending on size, it's honest value for a spring count this high, although you'll want to be sure a firm feel suits you before buying.
Key Features & what's inside
- Gel Infused Quilted Sleep Surface. A quilted top layer of M-Luxe Gel Memory Foam cushions your pressure points while drawing heat away from your body. You'll feel gentle cushioning without the surface warming up overnight.
- M-Luxe Cool Gel Memory Foam. This layer gently moulds to your body shape for full-body support and comfort. The gel infusion continues pulling heat away, keeping things fresh rather than clammy.
- Responsive Reflex Foam. Reflex foam contours to your shape while keeping the mattress feeling firm. It adds gentle cushioning without letting you sink too far.
- Pocket Springs. Full-size pocket springs adjust individually to your movements and weight distribution, which means orthopaedic support exactly where your body needs it. A layer of mini pocket springs sits alongside, refining that support at an even closer level.
- High-Density Support Foam Base Layer. A deep layer of Flex Foam anchors the mattress and promotes healthy spinal alignment. It provides the full-body support and tension relief the layers above build on.

Who's it NOT for?
This is a firm mattress, so if you prefer a soft, cradling feel, or you're a lightweight side sleeper who needs more give at the shoulder and hip, it's likely not for you. There's also no UK Single or Small Double option, so solo sleepers wanting a smaller size will need to look elsewhere.
MLILY Summit Ortho 2800 Cool Gel Hybrid Mattress
Is the MLILY Summit Ortho 2800 firm or soft?
It's a firm mattress. The reflex foam layer is designed to maintain that firm feel while still offering gentle cushioning, so it suits sleepers who want clear support rather than a plush, sink-in surface.
How many springs does the MLILY Summit Ortho 2800 have?
It has 2,800 full-size pocket springs, plus a separate layer of mini pocket springs. Each spring adjusts individually to your weight and movement, which means support stays targeted where your body needs it rather than spread evenly across the bed.
Does the MLILY Summit Ortho 2800 sleep cool?
It's built with cooling in mind. Both the quilted sleep surface and the M-Luxe Cool Gel Memory Foam layer beneath it are gel-infused to draw heat away from your body, so it should run cooler than traditional memory foam mattresses.
What guarantee comes with the MLILY Summit Ortho 2800?
The Mattress Next Day listing states an MLILY 5-year guarantee. Terms can vary by retailer, so it's sensible to confirm the guarantee details with whichever shop you buy from.
What sizes does the MLILY Summit Ortho 2800 come in?
It's available in UK Double, UK King and UK Super King, priced from £599 to £799 depending on size. There's no Single or Small Double option, which is a limitation if you want it for a smaller bed frame.
