Elastic cushion and furniture

Abstract

An elastic pad includes a pad body having a set of elastic modules and at least one replaceable pad layer stacked in a vertical direction. An outer covering is configured to cover the pad body. The outer covering includes a top covering portion, and a side enclosure covering portion connected via a detachable structure which allows disassembly or assembly of the side enclosure covering portion. The top covering portion covers a top surface of the pad body, and the side enclosure covering portion encloses and covers side surfaces of the pad body. The side enclosure covering portion can be disassembled and assembled to allow replacement of the pad layer without changing the set of elastic modules and the top covering portion. Elastic pads differing in thickness and hardness may be used, while improving comfort and cleanliness.
