MyBedFrames Pocket Spring Replacement Sofa Bed Mattress im Test

The MyBedFrames Pocket Spring Replacement Sofa Bed Mattress is a 10cm, medium pocket sprung mattress for 2-fold sofa beds whose original mattress is 10cm deep, which is the most common depth for that mechanism. MyBedFrames makes it in its UK factory in two-seater and three-seater widths and sells it direct with a five-year guarantee and free delivery to most of mainland Britain.

Sizes and prices

Prices are MyBedFrames’ at the time of writing (October 2026), shown against a higher RRP. Delivery takes 3 to 10 working days according to the product page, and the delivery FAQ confirms it is free to England, Wales and the Scottish lowlands.

Construction and feel

Each spring sits in its own fabric pocket, so it reacts on its own rather than pulling its neighbours down, and MyBedFrames describes the support as medium, 5 out of 10 on our scale. The product page lists the mattress as reversible. It does not publish a spring count or the make-up of the comfort layers, so we cannot compare it spring for spring with the 12cm Sofabed Gallery Ultimate Pocket Sprung; what it offers instead is the 10cm depth, which fits frames the 12cm mattress may not, and a guarantee period that Sofabed Gallery does not state.

Who it suits, and the contract version

Choose it if your 2-fold sofa bed currently has a 10cm sprung mattress that has gone lumpy and you want pocket springs in the same envelope. It is sold only in 112cm and 132cm widths, so a chair bed or a 144cm large double needs another maker. If the sofa bed is in a holiday let or guest house, the sister site HotelContractBeds sells a contract version described as Crib 5 compliant, at £249.90 and £291.55 in the same two widths at the time of writing.
