Assessed from the specification published by Mattress Online, captured September 2026, and from regular price comparison across our UK retail partners.
This is a sensible pick if you want a traditional pocket sprung feel at a modest price and you sleep better on a firmer surface. The medium to firm tension suits back sleepers and heavier bodies well, although lightweight side sleepers may find it a little unyielding. Yes, the fibre comfort layer is simpler than the foams and naturals found on pricier models, but it keeps the price down and avoids the heat retention some foams bring. If you buy from Mattress Online, the listing includes a 100-night trial, a 5-year guarantee, and free next day weekday delivery, with room-of-choice delivery available for £20.00 and old mattress removal for £35.00.
Key Features & what's inside
- Comfort Layer. Soft white fibre fillings sit at the surface, which means a cosy, slightly cushioned feel over the firmer springs beneath. It is a simple comfort layer rather than a deep plush one.
- Support System. 800 individual pocket springs, each sitting inside its own fabric pocket, move independently. In practice that means support tailored to your shape and less motion transferred across the bed when a partner moves.
- Cover. A damask cover, a finely woven and durable fabric that feels soft to the touch. Woollen tufts pass through the mattress to keep the fillings from shifting over time.

Who's it NOT for?
Skip this one if you prefer a soft, sink-in feel: medium to firm means noticeable resistance, and lightweight side sleepers may feel pressure at the shoulder and hip. Across owner reviews some mention wanting more edge support, so if you sit on the edge of the bed a lot, consider alternatives.
Sleepeezee Classic Ortho 800 Pocket Mattress
Across 238 reviews on the Mattress Online product page, the mattress holds a 4.5 rating, with owners reporting comfortable, supportive sleep and improvement in back pain. The main gripe is a wish for more edge support, a common one at this price.

How firm is the Sleepeezee Classic Ortho 800?
The listing describes it as medium to firm. You get clear support with a light layer of cushioning from the fibre fillings on top, which suits back sleepers and anyone who finds softer mattresses leave them aching. Lightweight side sleepers may find it slightly too firm.
Does the Sleepeezee Classic Ortho 800 come with a trial?
Mattress Online lists a 100-night trial with this mattress. That trial is the retailer's own offer rather than a Sleepeezee guarantee, so if you buy elsewhere, check that retailer's terms before ordering.
How many springs does the Classic Ortho 800 have?
It has 800 individual pocket springs. Each spring sits in its own fabric pocket and moves independently, so the mattress responds to your body shape rather than flexing as a single sheet, and you feel less of a partner's movement.
What guarantee does the Sleepeezee Classic Ortho 800 have?
The Mattress Online listing states a 5-year guarantee. As with the trial, confirm the guarantee terms with whichever retailer you buy from.
What sizes is the Sleepeezee Classic Ortho 800 available in?
Five UK sizes: Single, Small Double, Double, King and Super King, priced from £254 to £454 depending on size. The mattress is 24cm deep, so standard fitted sheets should fit without trouble.
