Manufactured in the UK by Highgrove Beds, the Nimbus Ortho 3ft 6 large single mattress boasts meticulous tailoring, generous layers of upholstery, and a traditional orthopaedic support.

Its upholstered in a quality damask cover that features a micro quilted finish; a process that sews the surface layers of fillings together in a quilted pattern and ensures they are held firmly in place.

Its open coil interior consists of hourglass shaped springs set in rows running from head to toe and connected into one single unit by a spiral wire, known as a helical wire.

To provide edge to edge support across its width, a thick rod-edge wire is attached around the perimeter of the spring unit. This prevents border breakdown and ensures the mattress retains its shape throughout its lifespan.

If you are looking for a well-constructed and affordable large single mattress with a firm support, you won’t go wrong with the Nimbus Ortho mattress from Highgrove Beds.
