The Tempur One Medium is currently listed in one size, UK Super King. That limited availability is a drawback if you want a smaller size, but if a Super King is what you're after, a medium feel from a memory foam specialist suits most back and side sleepers.

Why should you choose this mattress?
A medium firmness is the safest middle ground: soft enough to ease pressure on hips and shoulders for side sleepers, yet supportive enough for most back sleepers. If you're unsure what firmness you need, medium is where most people should start. It sits in premium territory, in line with Tempur's positioning as a specialist foam brand.
Key features & layer details
Stretch knit fabric cover
A soft, pliable cover that lets the fillings beneath contour to your body shape. It zips off and is machine washable at 40°C, so keeping it fresh is easy.
Memory foam
A body-moulding, pressure-relieving foam designed to reduce tossing and turning. It should cushion your hips and shoulders, which is useful if you sleep on your side.
Block foam
A durable, lightweight foam base used instead of springs, giving edge to edge support across the whole 20cm-deep mattress. You get the full sleeping area to use, though you won't get the bounce of a spring base.

Best suited for?
Side sleepers
The medium firmness is soft enough to ease pressure on hips and shoulders, which means side sleepers get cushioning where their body presses in most.
Back sleepers
Medium firmness stays supportive enough for most back sleepers, so the body feels held in a comfortable position without the surface being too hard.
Couples
The Super King size gives two people plenty of width, and the middle-ground medium feel is a safe starting point when partners have different preferences.
Combination sleepers
A medium feel is a sensible middle ground between soft and firm, which suits people who switch between their side and back during the night.
Skip this if you need anything other than a UK Super King, as that's the only size we currently see listed. It's also unlikely to suit anyone wanting a very firm feel, or shoppers on a tight budget, given the starting price.
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.

It's currently available in UK Super King only. If you need a smaller size, you may want to look at other options or check back later, as availability can change.
How much does the Tempur One Medium cost?
It comes in UK Super King only, and the price table on this page shows the current price. It sits at the premium end, which reflects Tempur's position as a specialist foam brand, although it's a fair amount to spend if you're on a tighter budget.
