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 the contouring comfort of memory foam without the sinking, stuck feeling that all-foam mattresses can give. The 1,800 individually cased pocket springs adapt to your movement, which means support that follows your shape rather than a flat, one-note surface, and a layer of mini pocket springs above them adds pressure relief while cutting down on motion transfer. That matters if you share a bed and one of you tosses and turns. Buying through MattressOnline, the sole listed retailer, gets you a 100-night trial, although it requires purchasing a mattress protector from them, plus free delivery to most UK locations. A 10-year guarantee is stated on the listing as a product feature.
Key Features & what's inside
- Knitted cover with Microquilted finish. A soft knitted cover with a micro-quilted finish, which means a smooth surface with a little added cosiness and warmth.
- Memory Foam. Memory foam cradles to your shape, which means a cushioned, cosy feel as soon as you lie down. It's the layer that gives this mattress its softer top comfort.
- Soft White Fibres. Soft synthetic fillings add to the cosy feel while staying durable and resilient. They're designed to hold their shape over time rather than compacting quickly.
- Mini Pocket Springs. Small, individually cased springs sit above the main spring unit, adding comfort and gentle pressure relief. They also help reduce motion transfer, so you'll feel less of a partner's movement.
- Pocket Springs. 1,800 traditional pocket springs, each encased in its own cloth pocket, adapt independently to your movement. This gives personalised support across the whole surface rather than the mattress moving as one piece.

Who's it NOT for?
Despite the Ortho name, the retailer listing describes this as a medium feel, so if you need a genuinely firm mattress, perhaps on medical advice, this probably isn't it. Hot sleepers should also be aware that memory foam can hold warmth. And if you dislike any memory foam contouring at all, look at a traditional pocket sprung model instead.

Is the Sleepeezee Luxury Ortho 1800 firm or medium?
The retailer listing describes the feel as medium, even though other listings give it as medium firm and the name includes Ortho. Treat it as a medium: supportive, but with a cushioned memory foam top rather than a hard orthopaedic surface.
How many springs does the Sleepeezee Luxury Ortho 1800 have?
It has 1,800 traditional pocket springs, each individually encased in a cloth pocket, plus a separate layer of mini pocket springs above them for added comfort and pressure relief.
Does the Sleepeezee Luxury Ortho 1800 come with a trial?
MattressOnline, currently the only listed retailer, offers a 100-night trial, but it requires you to buy a mattress protector from them. This is the retailer's own offer rather than a Sleepeezee guarantee, so check the terms wherever you buy.
How deep is the Sleepeezee Luxury Ortho 1800 mattress?
It's 28cm deep, a substantial build thanks to its two spring layers, memory foam and fibre fillings. Check your fitted sheets will stretch to that depth before it arrives.
What sizes is the Sleepeezee Luxury Ortho 1800 available in?
It comes in UK Single, Small Double, Double and Super King. There's no standard King in the listed sizes, which is an odd gap, so King buyers will need to size up or look elsewhere.
