After being let down by another supplier of pilates equipment I found this company on eBay and am so impressed. Within four working days of placing my order I received my Pilates Reformer Box which arrived well packaged, in perfect condition and the same quality and size as the ones provided in Pilates studios. It is a universal size and fits perfectly on my aero Pilates machine. The price is the going rate for these boxes. On the aero Pilates website they are around the same price but they are always out of stock. In fact they’ve become almost impossible to get hold of. Be warned of dodgy websites which say they’re in stock and once you hand over your money say they won’t be in stock until 2021 which happened to me though I did manage to get a refund after kicking up a fuss. This is an excellent company to deal with. I would highly recommend them.
