This seat is in really good condition for its age. It is double sided, with padding on both sides to provide two different heights. I believe it is covered with vinyl, but I am not 100% sure. Everything seems to be intact, no tears. I'm gonna guess the color is something like oxford blood, with very faint hints of black undertones. I tried to capture that in the pics the best I could. I do not have a lot of info on this item in regards to age and brand. My dad owned a bunch of chairs, including the brands Koken, Koch, Paidar, Belmont, etc. The chair this booster seat was with has been gone for several years, so I do not have the brand info from that. The closest to this booster seat I have seen online was in a listing for a mid-century Belmont. I have also seen a Koken 1940's chair with a similar-style booster seat. This is the best info I could come up with.
