Rocking chair i bought for $5

I got this chair at a garage sale.When I was cleaning the chair I could not find anything saying who made it.The top half of the chair is all wood.At the top back of the rocking chair it has about 6 snaps built into the wood to snap into place the back cushion.The seat bottom has a 14 inch square hole with 5 removable elastic bands.I took them out to look at them,at each end they had metal clips.I was looking at them and notice there was a patent number.So I went online and looked it up.The patent was for the straps,it was approved in 1958 but it was submitted in 1956.The top half of the chair is bolted to a metal bottom which consist of the following:three springs,a swivel part,and five feet with small wheels.I am trying to find out when it was made and who made it?
