Dunelm Mito Futon Mattress im Test

The Dunelm Mito Futon Mattress is a 12cm button-tufted futon in a cotton-blend cover with a fibre-blend filling, sold by Dunelm in single and double sizes and in more than ten colours. It is the replacement mattress for Dunelm’s own Mito futon frames and doubles as a roll-out spare bed; the product page pitches it as a space-saving solution where space is at a premium.

Sizes and prices

Prices vary by colour: in October 2026 several colours were reduced by 20% to £79.20, while others sat at the higher regular price, so compare shades before you order. Dunelm’s product images give a medium firm feel, a 12cm depth and a ten-year warranty, and Dunelm buyers rate it 4.2 out of 5 across 144 reviews.

Who it suits

The Mito is a guest-room futon. Fibre filling is light (about 7.5kg) and easy to roll, but it compacts faster than the foam or cotton-felt cores of hand-made futons, so nightly use will wear it out sooner. Note the length too: at 185cm it is 5cm shorter than a standard UK single or double, which matters if your guests are tall or if you plan to fit it to a frame made for 190cm futons.

Safety and care

As a new futon from a major UK retailer it falls under the Furniture and Furnishings (Fire) (Safety) Regulations, which require fire-resistant fillings and covers on upholstered furniture. Air it regularly if it lies on the floor, since a mattress that cannot breathe gathers moisture underneath.
