It is difficult to compare the quality and price of Mobility products. Most sellers and suppliers want to make a house visit as a lot of things are bespoke. All the dimensions and needs could be requested on their websites, but they are'nt. We had a bad experience with a house call salesperson and had to threaten to call the police before he would leave. This was not about mobility products. Mobility Compare is a good reference site to make contact with likely suppliers. They sent me the names of the three companies that would contact me by phone. I liked that as the market is vast and not easy to navigate.
