The appliance includes upper and lower support members having associated spaced apart end portions which form parts of the joint assemblies. Each joint includes a generally disc shaped connecting member disposed intermediate associated end portions of upper and lower support members. The end portions are secured to the connecting member for independent pivotal movement about parallel axes. Concealed stops carried by and disposed intermediate the end portions cooperate with the connecting member to limit pivotal movement of the support members relative to each other.
