Abstract The spring bridges of an undermattress are pro- vided with Lifting slats (9) which lift the unloaded mattress during the day for the purpose of better airing of the plywood springs (4, 5). During loading by a re- clining person, the lifting slats (9) fall back below the upper edge of the plywood springs (4, 5), so that the mattress is then supported normally. (Fig. 2)
