Why should you choose this mattress?
If you sleep on your back or front and prefer a bed that holds you up rather than lets you sink, this firm feel is the point of the whole design. The pocket springs work independently of one another, which means less motion transfer if you share the bed and support that follows your shape rather than tilting you towards a heavier partner. The wool blend layer is naturally temperature regulating, a genuine help if you run warm at night. It's made in the UK by an NBF-approved manufacturer, meets the BS7177: 2008 fire safety standard, and the listing states a Sleepeezee 10-year guarantee, which offers reassurance at a mid-range starting price.
Key features & layer details
Damask Cover
A breathable cover made from Belgian damask fabric. Breathability here means air can move through the surface, which helps the mattress feel less stuffy on warm nights.
Polyester and Wool Blend
A comfort layer blending polyester with wool, which is naturally temperature regulating. In practice that means it helps even out warmth rather than trapping heat against you.
Soft White Fibres
Fibre fillings made from 100% polyester, chosen for recovery and durability. They spring back into shape after use, which helps the surface resist dips over time.
1000 Pocket Springs
Up to 1000 springs, each pocketed so it works completely independently of the others. This gives targeted support and reduces the ripple you feel when a partner moves.

Best suited for?
Back sleepers
The firm feel is designed to hold you up rather than let you sink, so your body stays level and supported through the night.
Front sleepers
A firm surface with 1000 pocket springs keeps your hips from sinking too deep, which helps you stay level when lying face down.
Couples
Each pocket spring works independently, which means less ripple when a partner moves and support that follows your shape rather than tilting you towards a heavier partner.
Warm sleepers
The wool and polyester comfort layer is naturally temperature regulating and sits under a breathable damask cover, so the surface feels less stuffy on warm nights.
Budget buyers
It is described as good value for a UK-made, NBF-approved mattress, and it comes with a 10-year Sleepeezee guarantee for added reassurance.
This is a genuinely firm mattress, so lightweight side sleepers may find it a little too unyielding around the shoulder and hip. If you like a plush, sink-in surface or the contouring feel of memory foam, this traditional spring-and-fibre build probably isn't for you. No trial period is stated on the listing either, so check before you buy.
Save on an earlier or ex-display model
Some retailers still sell the earlier version of this mattress, or ex-display and returned stock at a lower price. These are the sizes where it costs less than the current model's best price.

FAQ's
Is the Sleepeezee Ortho Firm 1000 good for back pain?
It's a firm pocket spring mattress designed for targeted support, with springs that respond independently to different parts of your body. Firm support suits many back and front sleepers, although firmness alone doesn't treat back pain, and lighter side sleepers may find it uncomfortable. If pain is ongoing, speak to a professional first.
How deep is the Sleepeezee Ortho Firm 1000 mattress?
It's 25cm deep. That's a standard depth that most fitted sheets will accommodate without any trouble, so you shouldn't need special deep-pocket bedding.
Does the Sleepeezee Ortho Firm 1000 come with a guarantee?
The MattressNextDay listing states a Sleepeezee 10 Year Guarantee. As with any guarantee, it's sensible to confirm the terms with the retailer you buy from before ordering, since conditions can differ between sellers.
What sizes does the Sleepeezee Ortho Firm 1000 come in?
Five UK sizes: Single, Small Double, Double, King and Super King.
Is the Sleepeezee Ortho Firm 1000 made in the UK?
Yes. It's made in the UK by Sleepeezee, an NBF-approved manufacturer, and it meets the BS7177: 2008 fire safety standard at the Low Hazard level.
