Here's a post from a while back that had lost it's image links.
Someone was asking about Cogswell chairs just yesterday, so I thought I'd refresh this old post from 2013.
Michigan has a long held reputation for quality furniture manufacturing. This midcentury Cogswell reclining chair is from The Luxury Furniture Corp. of Grand Rapids aka "Furniture City". My client remembers her dad driving the family around town weekends in their Studebaker, on the hunt for good furniture all the while admiring their city's industry and teaching the kids a thing or two in the process. This chair was one such piece she remembered as being purchased during one of their family outings.
These chairs from the 40s/50s are often platform rockers - this one has a simple construction in its base that allows it to tilt back or recline in just one position. Sinuous springs or "S" springs need no attention other than a new burlap cover + spring pad to keep all padding above it intact. But they are double spring systems, with a short coil spring unit in cushion that sits on top of sinuous attached to frame.
There are a few trim panels, or just strangely shaped and applied pieces to deal with because of the very shape of the chairs. No modifications will be made by me, I'll redo it as it was before only I'll close that front post edge better than the previous upholsterer.
