At 26cm deep, the Sealy Tudor Contract pairs soft white fibre fillings with PostureTech Core Support Springs, which means a little softness on the surface over a solidly supportive core. It comes in four UK sizes, from Single to Super King, with a 5 year guarantee. It's handcrafted in the UK and meets Crib 5 fire standards, a contract-grade rating that makes it suitable for guest houses and rental properties as well as homes. If you want genuinely firm support, this is built for exactly that.

Why should you choose this mattress?
Choose the Tudor Contract if firmness is the point. The PostureTech Core Support Springs use varied tensions and shapes to give full-body support and pressure relief, while the soft fibre comfort layer stops the surface feeling harsh. It carries reassuring credentials: OEKO-TEX certification on the cover, National Bed Federation approval, and a BugShield-treated damask cover. Yes, it's a firm, fairly traditional build rather than a plush hybrid, but that simplicity tends to mean durability, and the fillings are designed to hold their shape. It's reasonably priced for a UK-made contract-grade mattress. Mattress Online lists a 100-night trial and free delivery in 2-3 weeks, so check terms wherever you buy.
Key features & layer details
Comfort Layer
Soft white synthetic fibres sit on top, which means a cosy initial feel rather than the boardy surface some extra firm mattresses have. They're durable and resilient, designed to keep their shape over time.
Support System
PostureTech Core Support Springs use unique shapes and varied tension across the unit, which means support that adapts to different parts of your body. The aim is full-body support with pressure relief, giving the mattress its sturdy, extra firm character.

Best suited for?
Holiday lets and hotels
Crib 5 fire standards give this mattress a contract-grade rating, which means it suits guest houses and rental properties as well as homes.
Guest rooms
A BugShield-treated damask cover and fillings designed to hold their shape mean a spare bed that stays fresh and supportive between visits.
Back sleepers
Extra firm PostureTech Core Support Springs use varied tensions to give full-body support, which means a flat, steady feel under the back.
Heavier sleepers
A sturdy extra firm spring core with varied tensions resists sinking, while the soft fibre layer on top keeps the surface from feeling harsh.
Allergy sufferers
OEKO-TEX certification on the cover and a synthetic fibre comfort layer mean a straightforward build without natural fillings.
This is Sealy's firmest rating, so it's a poor match if you like a soft or medium feel. Lightweight side sleepers in particular may find it too unyielding at the shoulder and hip. Anyone wanting memory foam contouring or a plush pillow top should look elsewhere.
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
How firm is the Sealy Tudor Contract mattress?
It's rated Extra Firm, Sealy's firmest rating, described as highly supportive with a very firm, sturdy feel. That suits people who want serious orthopaedic-style support, although lighter sleepers may find it a little too solid.
What is the Sealy Tudor Contract mattress made of?

Does the Sealy Tudor Contract come with a trial or guarantee?
The mattress carries a 5 year guarantee. Mattress Online lists a 100-night trial, but that trial is the retailer's own offer rather than a Sealy policy, so it may not apply if you buy elsewhere.
