Why should you choose this mattress?
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. It's good value for a spring count this high, although you'll want to be sure a firm feel suits you before buying.
Key features & layer details
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.

Best suited for?
Back sleepers
The firm feel and responsive reflex foam keep you supported without sinking too far, which suits lying flat on your back.
Front sleepers
Firm support from the pocket springs and reflex foam layer helps stop your middle sinking into the mattress when you lie on your front.
Warm sleepers
A gel-infused quilted surface and M-Luxe Cool Gel Memory Foam draw heat away from your body, so the bed feels fresher overnight.
Couples
With 2,800 pocket springs plus a layer of mini pocket springs, support stays consistent when you shift position or share the bed.
Allergy sufferers
The mattress is certified hypoallergenic, which makes it a sensible choice if you want bedding that suits sensitive sleepers.
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.
Save on an earlier or ex-display model
Some retailers still sell the earlier version of this mattress, or ex-display and returned stock at a lower price. These are the sizes where it costs less than the current model's best price.

FAQ's
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. There's no Single or Small Double option, which is a limitation if you want it for a smaller bed frame.
