The Rainbow is a stylish & modern mattress that comes in a choice of 5 attractive colourways & for those of you who find a single too small, a 3ft 6 is an ideal size. The large single Rainbow is upholstered in a durable cotton cover that benefits from a deep quilted finish that attaches the outer cover to the surface layers of filling. At the core of the mattress is a strong open coil spring system that is made up of hourglass shaped springs set in rows & connected into one unit by a spiral helical wire. A thick 6 gauge rod-edge wire is attached to the perimeter of the spring system. This prevents breakdown of the border & ensures the interior retains its shape throughout its lifespan. The mattress is available in pistachio, natural, navy, red or pink. Simply choose your preferred colour from the options tab above.
