Extra firm mattresses are a small corner of the market, and this one comes from a long-established British maker. The pocket springs respond to each sleeper separately, which means more even support if you and a partner are different weights. Wool and silk fillings help with temperature, useful because firmer mattresses hold you on the surface where heat can build. The fabric also features SleepCalm technology with Valeria flowers woven in. It's turnable, which is increasingly rare and should extend its useful life, though it does mean flipping a 26cm mattress now and again. MattressNextDay lists a 10-year guarantee and free next day delivery, delivered flat, but check guarantee terms with Sleepeezee if buying elsewhere.
Key Features & what's inside
- Damask Cover. A breathable Belgian damask fabric cover. It lets air move through the sleep surface, which helps if you run warm at night.
- Comfort Fillings. A blend of British wool and silk. Both are natural fibres that wick moisture, so the surface feels comfortable without trapping heat.
- Support Layer. A layer of Ecobond that supports your spine and relieves pressure whatever position you sleep in. This is where the extra firm character of the mattress comes from.
- Comfort Fillings. Polyester and cotton layers with good rebound and recovery, which means the mattress springs back to shape rather than developing body impressions quickly.
- Support System. 1,600 barrel-shaped pocket springs, each mounted in its own fabric pocket and working independently. You get support that follows your body's shape, and less motion transfer from a restless partner.

Who's it NOT for?
This is rated extra firm, so it's a poor match for side sleepers, who need some give at the shoulder and hip, and for lighter people who won't sink in enough to feel supported. If you prefer a soft, cushioned, sink-in feel, look elsewhere. It also needs turning, which some will find a chore.

How firm is the Sleepeezee Ortho Bespoke Silver 1600?
It's rated extra firm, the firmest end of the scale. That suits back and front sleepers who want a solid, supportive surface, particularly heavier people. Lightweight and side sleepers are likely to find it too hard.
Does the Sleepeezee Ortho Bespoke Silver 1600 need turning?
Yes. The comfort layers are double-sided, so it's a turnable mattress. Flipping it periodically evens out wear on the fillings and should help it last longer, though at 26cm deep it's a two-person job.
How many springs does the Ortho Bespoke Silver 1600 have?
It has 1,600 barrel-shaped pocket springs, each housed in its own fabric pocket. They compress independently, which means the mattress responds to each sleeper's weight separately and reduces movement transferring across the bed.
What guarantee comes with the Sleepeezee Ortho Bespoke Silver 1600?
MattressNextDay lists a 10-year guarantee on its product page. Because that's a retailer listing rather than Sleepeezee's own site, it's sensible to confirm the guarantee terms with the manufacturer, especially if you're buying through a different retailer.
What sizes does the Sleepeezee Ortho Bespoke Silver 1600 come in?
It's available in UK Single, Small Double, Double, King and Super King, priced from £599 to £1,099 depending on size.
