Abstract
A mattress for use on a bed and settee comprises a spring unit, at least one cushion, a protection layer arranged between the spring unit and the cushion, and an outer covering for covering these component members. The protection layer includes a frame located at the circumference and outside of the spring unit, and a net tensioned inside the frame, the protection layer being made of synthetic resin and having the frame and net formed integral thereto. The frame has a flange with which end turns of coil springs arranged in the spring unit and adjacent to the frame can be contacted. The frame of each protection layer provided with the flange has sufficient rigidity and serves as a reinforcing member.

A mattress for use on a bed and settee, comprising:
- a spring unit including a plurality of compression springs arranged side by side and connected flat to one another, said spring unit having upper and lower surfaces;
- a resilient cushion disposed on at least one of the upper and lower surfaces of the spring unit;
- a protective layer disposed between the spring unit and the cushion so as to prevent the cushion from contacting the spring unit, said protective layer being integrally formed of a synthetic resin and including:
- a frame located at the circumference and outside of the spring unit,
- a net stretched within the frame, and
- a flange extending substantially vertically from the frame to surround the periphery of the spring unit, said frame and flange being stiffer than said net so as to render the peripheral portion of said protective layer less susceptible to elastic deformation than said net;
- and
- an outer covering for covering the spring unit, cushion and protective layer.
