Sleepeezee InMotion Eco 1000 Pocket Adjustable Mattress im Test

The Sleepeezee InMotion Eco is a 25 cm pocket sprung mattress designed to bend with an adjustable divan. It pairs 1,000 traditional pocket springs with layers of recycled polyester fibre and uses no foam at all. Sleepeezee makes it in Rochester, Kent, and sells it only through retail partners; MattressNextDay lists it in four adjustable sizes at a regular £399 for the 75x200 small single (October 2026).

Why it suits an adjustable base

A mattress on a motorised base folds every time you raise the head or foot section, so it has to flex without the springs or fillings taking a set. Sleepeezee describes the InMotion Eco as designed to work with an adjustable divan, flexing into any position, which is a clearer statement than most makers give. The National Bed Federation sets two tests for any mattress on a moving base: it must be flexible enough to bend with the base, and the cover should stretch rather than ruck as the bed folds. The InMotion Eco has a soft knitted cover and a single-sided, non-turn build, so it stays the right way up on the base and never needs flipping.

Sizes and prices

Adjustable bases are usually 200 cm long rather than the 190 cm of a standard UK single or double, and the InMotion Eco follows them. For a king or super king adjustable bed with two independent motors you buy two small singles or two singles and place them side by side; Sleepeezee also lists a super king zip-and-link version through other stockists.

At the time of writing MattressNextDay showed the small single reduced to £399, with delivery times from next day to two weeks depending on the size.

Who it suits, and the drawbacks

Sleepeezee rates the feel medium-soft, which we place at 4 out of 10. That suits back and side sleepers who sit up to read or raise their legs in the evening, and the all-fibre build breathes better than a dense foam slab. It is less suited to front sleepers, and fibre does not contour the way memory foam does, so anyone who wants a deep, pressure-relieving hug should look at a foam model. No maximum sleeper weight is published, and MattressNextDay stocks only the four sizes above.
