Wittmann offers a highly convenient option for double beds with separate bases in the shape of swing-away bed halves. The advantages are obvious. Allergy sufferers are not alone in appreciating a system that makes thorough cleaning under the bed easier than ever before. The fittings disappear into the upholstery, and there is no outward sign of this technical refinement. There is a choice of ultra-quiet casters to suit different types of floor. The casters are easy to fit and detach. Swing hinges are available for Somnus II, III, IV and V with 160cm, 180cm and 200cm wide bases.
