After disassembling the office chair of this video, I found the bolsters and the other portions were refilled/foamed after joining/sewing down the pieces together. I mean the vinyl, foam and fabric backing were not attached in the traditional way. A bag system was used instead to make the cover.
The deteriorated vinyl of the cover was almost thoroughly peeled off, appearing as if it was done in a combination of black vinyl and grey fabric.|
They used zippers to open the mouths to push the padding/foam inside. In fact this is a fast way to refill the padding.
I used hand sewing to close the opening instead. Not advisable because it takes too much time.
To tackle the reupholstery project I used two methods to find out which one would be the best.
My first way was with the seat cushion. I sew the pieces together as if I were sewing a regular foamed cover. It was really a tedious experience using my flat bed sewing machine. Not really an easy task.
In the second way, for the backrest I tried to replicate the same way how the old cushions were upholstered. It came out much easier as you can see in the video. The issue arose at fitting time. It was really a frustrating episode because of using the same old foam as the customer requested. The outcome was full of wrinkles and loose bolster. I had to reinforce those old foams with pieces of harder foams to get a nicer fitting.
In conclusion, to get a nice fitting/refilling for the bolsters and other pieces we should use a high density foam plus a softer foam or a layer of dacron batting over.
A non-fraying and non-stretching fabric/thin canvas could be used for the backing on the reverse side of the cover. I think zippers are a good way to open and close the refilling mouths.
Office chairs' upholstery is also part of our trade and a car upholsterer is also able to carry out.
I hope you find this video useful and inspire yourself to make your own upholstery projects!
