Assessed from the specification published by Mattress Online, captured September 2026, and from regular price comparison across our UK retail partners.
This is a mattress built around firm support with a softer touch on top. The 2000 pocket springs work independently, so you get support tailored to where your body needs it, with less motion transfer if you share the bed. Above the springs, natural wool and cashmere wick moisture and help regulate temperature, which means you're less likely to overheat than on an all-foam alternative. It carries National Bed Federation approval and is handcrafted in the UK. Yes, it's single-sided so you can't flip it, but rotating it every few months keeps wear even. If you sleep on your back and want a firmer feel, this one suits well.
Key Features & what's inside
- Knitted cover. A soft knitted cover that adds a cosy, warm finish. It's designed to aid airflow and breathability, which means a slightly cooler sleep surface.
- Wool and cashmere blend. A plush layer of natural wool and cashmere with breathable, moisture-wicking properties. In practice, this helps regulate your body temperature through the night.
- Soft white fibres. A layer of soft white fibres that rounds out the feel with extra comfort. It also adds breathability and helps the mattress last.
- Pocket springs. 2000 traditional pocket springs, each encased in its own fabric pocket so it can move independently. This means the support adapts to your shape rather than pushing back as one unit.

Who's it NOT for?
This is a genuinely firm mattress, so lightweight side sleepers or anyone who likes a sink-in, cushioned feel should look elsewhere. It's single-sided, so it can't be flipped, only rotated. Some owners also find it heavy and awkward to move, which matters if you'll be rotating it alone.
Sleepeezee Ultimate Ortho 2000 Pocket Mattress
Across verified owner reviews on the mattressonline.co.uk product page, customers report improved sleep quality and relief from back pain and joint stiffness, with the firm support particularly helpful for those with back issues. Some do find the mattress heavy and difficult to manoeuvre.

How firm is the Sleepeezee Ultimate Ortho 2000?
It's rated firm. That means a supportive, flatter feel with limited sink, which back sleepers and people with back issues tend to get on with. The wool, cashmere and soft fibre layers add a little surface comfort, but this is a firm mattress rather than a medium-firm one.
Does the Sleepeezee Ultimate Ortho 2000 come with a trial?
Mattress Online lists a 100-night trial on this mattress. That trial is the retailer's own offer, so if you buy elsewhere the terms may differ. Check the returns policy of whichever shop you order from before you commit.
How many springs does the Sleepeezee Ultimate Ortho 2000 have?
It has 2000 pocket springs, each sewn into its own fabric pocket. Because the springs move independently, support follows the contours of your body and movement on one side of the bed transfers less to the other.
Can you flip the Sleepeezee Ultimate Ortho 2000?
No. The retailer listing states it's single-sided, so you rotate it every few months rather than flipping. Worth bearing in mind that some owners find it heavy to move, so you may want a second pair of hands for rotation.
What guarantee does the Sleepeezee Ultimate Ortho 2000 have?
Mattress Online lists a 10 year guarantee with this mattress. As that appears on a retailer listing rather than Sleepeezee's own page, confirm the guarantee terms with your retailer at the point of purchase.
