The Tri-Comfort is a multi-layer foam adjustable bed mattress from Adjust-A-Bed, designed and handmade in Great Britain and built specifically for use with an adjustable base. It's constructed from carefully layered foams of differing densities, topped with a breathable Air-Lite Comfort Foam layer and reinforced edge-to-edge support, with a removable cover for easy cleaning. Available in a choice of Soft, Medium, or Firm tension, it lets you tailor the feel to your individual comfort needs while keeping the same supportive, foam-only construction underneath.
A multi-layer foam adjustable bed mattress with a breathable Air-Lite Comfort Foam layer, available in a choice of Soft, Medium, or Firm tension, best suited to sleepers who want to select their own comfort level with consistent support through every base position.
Soft Feel: Our softest tension, designed for maximum comfort and pressure relief. Ideal for side sleepers, this feel allows shoulders and hips to gently sink into the mattress for a cushioned, cosy night's sleep.
Medium Feel: The Goldilocks option - not too firm, not too soft. Medium is the most versatile firmness level, balancing comfort and support in a way that suits most sleeper types.
Firm Feel: A supportive, solid feel designed to keep your body well supported throughout the night. Ideal for back and front sleepers, or those who prefer a firmer sleeping surface.

Vs choosing a single-tension adjustable mattress: Most adjustable bed mattresses come in one fixed tension, so you need to know in advance whether you want a softer or firmer feel. The Tri-Comfort removes that guesswork - Soft, Medium, and Firm are all available in the same model, so you can pick the tension that suits your body and sleep style directly, without comparing across different mattresses in the range.
Vs pocket-sprung adjustable mattresses: This mattress uses a foam-only, multi-layer construction rather than pocket springs. Foam gives a more uniform, contouring feel across the whole surface, while pocket springs respond more locally to movement and typically suit couples or combination sleepers who want more targeted give. If you prefer the specific feel of springs, a pocket-sprung model elsewhere in the range may suit you better.
Vs buying with a base: This mattress is also available together with a matching Adjust-A-Bed adjustable base - useful if you are buying your first adjustable bed and want guaranteed compatibility between base and mattress. If you already have a compatible adjustable base and simply want to upgrade the mattress, this mattress-only option lets you do that without replacing the whole bed. The paired bed and base listing can be found here.
The Tri-Comfort is backed by Adjust-A-Bed's 5-year manufacturer's guarantee against defects in materials and workmanship. Given the multi-layer foam construction and reinforced edge support, this is a mattress built for consistent comfort over time, and the guarantee reflects that.
The Tri-Comfort delivers balanced, multi-layer foam support in your choice of Soft, Medium, or Firm tension, designed and handmade in Great Britain and backed by a 5-year guarantee. If you want to select your own comfort level, or simply want a foam-only mattress that holds its shape through every adjustable position, this is one to consider.
