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.

Key benefits
- Fits compact rooms: At 90cm wide it leaves room for a desk or wardrobe in a small bedroom, which matters when the bed is competing for floor space.
- Built for guest and rental use: The Crib 5 contract rating and BugShield-treated cover suit landlords and guest houses, where a UK single often furnishes each letting room.
- Firm support for growing sleepers: PostureTech Core Support Springs give a sturdy, supportive base that suits older children and teens who need proper spinal support rather than a soft sink-in feel.
- Softened surface: Soft white fibre fillings take the edge off the extra firm core, so guests get a little initial comfort rather than a boardy first impression.
- Cheap, easy bedding: Standard single sheets and a 135 x 200cm duvet fit, and both are the most widely stocked bedding of any UK size.
This size suits you if...
You're furnishing a spare room, student let or guest house and want a durable, contract-grade mattress in the standard one-person size, or you're buying for a teenager who sleeps better on a genuinely firm surface. It also suits a solo adult in a compact room who prefers extra firm support and needs the 90cm width to keep floor space free.
Consider another size if...
You're an adult who wants space to spread out, or a couple. The UK single is 45cm narrower than the UK double at the same length, so we'd recommend the UK double instead; allow at least 2.6m x 2.8m for it.

FAQ's
What room size do I need for the Sealy Tudor Contract in a UK single?
We suggest allowing at least 2.1m x 2.8m of floor space. That gives you a walkway alongside the 90 x 190cm mattress, which matters in a child's room where a wardrobe and desk are fighting for the same wall, or in a spare room that doubles as an office.
Can I use the Sealy Tudor Contract single on a bunk or mid sleeper frame?
The 90 x 190cm footprint matches standard UK bunk and mid sleeper frames, but this mattress is 26cm deep, which is on the taller side for a raised bed. Check your frame's maximum mattress depth and guard rail height before buying, as many bunks are designed for shallower mattresses.
Is the Sealy Tudor Contract single a good choice for a guest room?
Yes, arguably its best use. Its Crib 5 contract rating means it's built for guest houses and rentals, and the extra firm feel copes with guests of different weights. If your spare room takes two beds rather than one, a pair of UK singles is a flexible way to sleep two visitors.
Is the Tudor Contract in a UK single suitable for a child or teenager?
For older children and teens who need firm support, yes: the PostureTech springs give a sturdy base and the fibre top softens the surface. It's a poor match for a lightweight child who sleeps on their side, though, as this is Sealy's firmest rating and may feel unyielding at the shoulder and hip.
How much bigger is a UK double than the single Tudor Contract?
The UK single is 45cm narrower than the UK double, and the two are the same length. If you're a solo adult who tosses and turns, that extra width is the main reason to size up; allow at least 2.6m x 2.8m of floor space for the UK double.
