The bed frame is 60 mm (2 3/8 inch) thick and made of four parts, whereby the two boards at the ends are firmly connected in place. The solid wood bed rests on runners with adjustable feet and floats 60 mm (2 3/8 inch) high. The mattress rests 190 mm (7 1/2 inch) within the frame, however support brackets may be adjusted to reduce this to 150 mm (6 inch) or 110 mm (4 1/3 inch). Slatted frames need to be ordered separately. e15
