Foam mattress with covering sheet and moulded part - has T=shaped cavities alternating with inverted T=shaped partitions in moulded part

摘要

The foam mattress enables the body weight to be evenly distributed, and an accumulation of heat and humidity to be avoided. The matrees consists of a moulded part (2), with a covering sheet (1). The moulded part, has a number of 'T' shaped cavities (4) in it, opening towards the covering sheet and widening out towards the centre running across it. Each cavity (4) has an opening (5) and a wide section (6). Between the cavities there are walls (7) which are the same shape as the T-shaped cavities with wide sections (9) and connecting sections (8). The space between every two walls coincides with that between two slats (3) of the grid supporting the mattress.
