Orthocoil Mattress
The Orthocoil Mattress is built on an open-coil orthopaedic spring system, with interconnected coils that flex together rather than independently. It is a firmer, more uniformly supportive design than a pocket-sprung mattress, traditionally chosen for back support and durability over plush comfort.
Open-coil mattresses suit sleepers who want a noticeably firm, supportive feel underneath them and who do not need the contouring response of pocket springs. They are also commonly recommended for sleepers with lower-back stiffness who benefit from a flatter, less yielding surface.
The Orthocoil sits on any flat or sprung base, including Kumo bed frames, divan bases and ottoman lift-up frames. It is available in the five standard UK sizes: 3FT Single, 4FT Small Double, 4FT6 Double, 5FT King and 6FT Super King.
The Orthocoil is the most accessible price point in the Kumo mattress range. If you want a firm, durable mattress without paying for pocket-spring technology you may not need, this is a sensible pick.
