Abstract
Improved water bed construction where, in one embodiment, two spaced inflatable members are positioned along the two lateral edges within a water bed frame with a separate water filled mattress being positional thereover with the conventional safety or water liner, wherein the inflatable members are filled with liquid or gas so as to have less resiliency than the water filled mattress portion, whereby ease of entry and exit onto the water mattress is facilitated. In another embodiment a liquid or gas supply means with appropriate controls is utilized so as to selectively and preferentially fill the lateral inflatable members to desired pressure, or alternately, to deflate same to selectively alter the resiliency thereof to facilitate supporting conditions of the water mattress.
