Why should you choose this mattress?
The firm feel suits you if you like to sleep on top of your mattress rather than sink into it. The 2000 pocket springs adapt to the weight and movement of each sleeper, and the natural fibres are described as temperature-regulating, with polyester and cotton layers that wick away moisture. Because it's double-sided, you can flip and rotate it seasonally to spread the wear. The tufted, glue-free finish and hand side-stitched spring unit point to careful construction, and Wentworth Mercer gives it a 10-year guarantee. It suits most back sleepers, although side sleepers who want a lot of cushioning may find it too firm.
Key features & layer details
Wool, cashmere & silk layers
Two layers of a wool, cashmere and silk blend form the top. They give a plush, cosy surface over the firm feel beneath.
Polyester fibre layers
Two further layers of polyester fibres add comfort and increase airflow, which means the mattress breathes better.
Polyester & cotton layers
Two layers of polyester and cotton wick away moisture, which helps you stay drier through the night.
Pocket spring core
A core of 2000 pocket springs in cloth pockets that adapt to the weight and movement of every sleeper. This gives the firm, supportive base.

Best suited for?
Back sleepers
The firm feel and supportive core of 2000 pocket springs suit this position, as the mattress keeps you lying on top of it rather than sinking in.
Warm sleepers
Natural fibres described as temperature-regulating, plus polyester and cotton layers that wick away moisture, help you stay drier and more comfortable through the night.
Couples
The 2000 pocket springs sit in individual cloth pockets and adapt to the weight and movement of each sleeper, and the UK double, king and super king sizes give room to spread out.
Holiday lets and hotels
It is built for private and rental use, and the double-sided design lets you flip and rotate it through the year to spread the wear.
If you prefer sleeping on a soft or medium mattress, this might not be the best choice. It's rated firm, and the wool, cashmere and silk layers add a plush top feel without changing that rating. Lighter side sleepers who want to sink in may feel it pushes back. It's also flippable, so it's heavier work to turn than a one-sided mattress.
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 Wentworth Mercer 2000 Pocket Pro?
It's rated firm. The wool, cashmere and silk layers give the surface a plush touch, but the feel underneath stays firm. It suits sleepers who want solid support, while those who prefer a softer feel may find it too firm.

It comes in a UK single (90 x 190cm), UK double (135 x 190cm), UK king (150 x 200cm) and UK super king (180 x 200cm). The super king is listed with a tolerance of plus or minus 2cm.
How deep is the Wentworth Mercer 2000 Pocket Pro?
It's 29cm deep in every size. That's enough to need a bit of thought if your sheets are shallow, so check your fitted sheet depth before buying.
Can you flip the Wentworth Mercer 2000 Pocket Pro?
Yes, it's double-sided, and the advice is to flip and rotate it seasonally. Doing that spreads the wear more evenly. The tufted finish is glue free, and the spring unit is hand side-stitched.

Wentworth Mercer gives it a 10-year guarantee. Mattress Online offers its own 100-night comfort trial, and exchanging under it requires buying a mattress protector from them.
