    Perfect fit for my antique chair

    Posted by Kate on Mar 10th 2022

    Contacting customer service was really helpful in making sure I ordered the right size. I inherited an antique chair that had very odd sized casters, and it was very hard to find ones that would not ruin my hardwood floors. These work really well.

    Custom chair caster

    Posted by Jon on Jan 19th 2022

    I ordered a caster with a 3/8 x 1 1/8 stem and it fit perfectly on my collection of pollock chairs from knoll. I have looked around for this size and finally I stumbled across this site and now I am happy. Casters at last!

    I did not have the standard 11 mm size of wheel casters for my sewing chair. This vendor supports all sizes used in the past. Great quality.

    The size I needed was not exactly one of the sizes. I used the vendor's contact us and was given exceptional customer support from them. They asked for a picture and suggested the size to use. This turned out to work perfectly and I'm very happy with the replacement. The customer support showed by this company is outstanding.
