Assessed from the specification published by Mattress Online, captured September 2026, and from regular price comparison across our UK retail partners.
This mattress makes sense if you want a hybrid feel without a hybrid price. The pocket springs adapt to movement individually, which means you feel support where you need it rather than one flat push back, and the open cell memory foam is designed to shift heat away rather than trap it, so it should sleep cooler than standard memory foam. At 20cm deep it's shallower than some hybrids, but that keeps it light and easy to handle. It comes rolled, and buyers mention it's simple to manoeuvre into place. Five UK sizes are available, from single up to super king.
Key Features & what's inside
- Knitted cover. A soft knitted cover that adds a cosy, warm finish to the sleep surface. The knit construction is breathable, which helps air move through the top of the mattress.
- Luna Fusion Cool Memory Foam. A 2cm layer of Luna's Fusion Cool Memory Foam with an open cell structure, which means air moves through it and heat disperses rather than building up. It moulds around your body to ease pressure, giving a cooler feel than standard memory foam.
- Reflex Foam. Two layers of reflex foam sit beneath the memory foam, adding cushioning that moulds to your shape. This helps keep your spine aligned as you settle in.
- Pocket Springs. 1,000 individual springs, each encased in its own cloth pocket, respond to movement separately. That means support is distributed to each part of your body rather than the whole surface moving as one.

Who's it NOT for?
If you want a genuinely soft, sink-in feel, look elsewhere: this is listed as medium, and owners often describe it as firmer than that. Anyone after a deep, luxurious build may also find 20cm a little shallow. The 2cm memory foam layer is on the thin side if you love a pronounced hug.

Is the Luna Memory 1000 firm or medium?
It's listed as medium firmness. That said, customer reviews often describe it as being on the firmer side, so if you're a lightweight side sleeper expecting a plush medium, it may feel a touch firmer than you'd like.
Does the Luna Memory 1000 come with a trial?
Mattress Online lists a 100-night trial with this mattress. Bear in mind that's the retailer's own offer rather than a manufacturer promise, so check the terms wherever you buy.
How deep is the Luna Memory 1000 Pocket Hybrid?
It's 20cm deep, which is shallower than many hybrids. Standard fitted sheets should fit easily, but if you're used to a tall, hotel-style mattress it may feel a little low profile.
Does the Luna Memory 1000 sleep hot?
It's designed not to. The memory foam layer has an open cell structure to increase airflow and dispel heat, and the knitted cover is breathable too, so it should feel cooler than standard memory foam. If you're a very hot sleeper, no foam hybrid is entirely immune, but this one takes sensible steps.
What guarantee does the Luna Memory 1000 have?
Mattress Online lists a 10-year guarantee with this mattress. Since that comes from a retailer listing rather than Luna's own site, confirm the guarantee terms with your retailer before you order.
