Patent number: 7278691Abstract: An article of furniture having a removable seat or back cushion. The design includes a frame having a recessed cushion support surface that creates a rim that defines a pocket that allows a seat or back cushion having first and second portions to be securely attached to the article. The first cushion portion is placed adjacent the recessed support surface, and a peripheral lip of the first portion is placed into the pocket in order to secure the cushion to the frame. The second portion provides the user contact surface. In one embodiment, the second portion substantially obscures the edge of the rim from view. As a result, the present invention maintains the aesthetic appeal of an article of furniture having removable seat or back cushions, while providing a more secure and relatively unobvious attachment of the cushions.Type: GrantFiled: May 19, 2006Date of Patent: October 9, 2007Assignee: Zhejiang Yongqiang group Co., Ltd.Inventor: Guangqiang Xiang
