If you wake with a stiff lower back, a firm mattress like this one keeps your spine on a more even line, and the 1600 pocket springs adapt to your movement to spread support across each part of your body. The soft white fibre comfort layer takes a little of the edge off the firmness, so you get a cosy surface without losing the sturdy feel underneath. The tufted cover holds the fillings in place, which means the mattress should keep its shape rather than developing dips. Yes, it lacks any natural fillings, but the synthetic fibres are durable and resilient, and they help keep the price down. It carries a 10-year guarantee as listed by the retailer.
Key Features & what's inside
- Cover. A soft knitted fabric with a traditional tufted design. The tufting anchors the fillings in place, which means the surface stays even and the sturdy feel lasts.
- Comfort Layer. Soft white synthetic fibres that create a cosy top feel. They are durable and resilient, so they hold their shape rather than flattening quickly.
- Support System. 1600 traditional pocket springs, each encased in its own cloth pocket. They adapt to your movement individually, which means support is distributed to each part of your body rather than the whole surface tilting when you shift.

Who's it NOT for?
This is a genuinely firm mattress, so lightweight sleepers and dedicated side sleepers may find it puts too much pressure on the shoulder and hip. If you prefer a plush, sink-in feel, or want natural fillings such as wool, look elsewhere: the comfort layer here is entirely synthetic.

Is the Sleepeezee Luxury Ortho 1600 mattress firm or soft?
It is a firm mattress. The 1600 pocket springs give solid, adaptive support while the soft white fibre layer adds a slightly cosier surface, so it feels firm rather than hard. It suits back and front sleepers best; lighter side sleepers may find it too unyielding.
Does the Sleepeezee Luxury Ortho 1600 come with a trial period?
Mattress Online lists a 100-night trial with this mattress, but that is the retailer's own offer rather than a Sleepeezee guarantee, and it requires buying a mattress protector from them to qualify. If you buy elsewhere, check that retailer's returns terms before ordering.
How long is the guarantee on the Sleepeezee Luxury Ortho 1600?
The retailer listing shows a 10-year guarantee. As with the trial, confirm the guarantee terms with whichever retailer you buy from, since this figure comes from the Mattress Online listing rather than Sleepeezee's own page.
How deep is the Sleepeezee Luxury Ortho 1600 mattress?
It is 25cm deep. That is a fairly standard depth, so most fitted sheets should go on without a struggle, and it will not tower awkwardly over a low bed frame.
What sizes does the Sleepeezee Luxury Ortho 1600 come in?
It is available in UK Single, UK Small Double, UK Double, UK King and UK Super King, with prices ranging from £449 to £859 depending on the size you choose.
