We had purchased this wheelchair in June 2019 and by April 2020, the backrest arm had already broken... Its use was only indoors... For outdoors, we have another wheelchair... The overall construction is cheap, the connections are made of plastic, and the backrest arms consist of three pieces that are connected to each other with screws and bolts instead of being a solid tube. Some plastic parts have also cracked... I would not recommend buying it because it is a cheap construction and a waste of money... It is better to spend a little more and get something more reputable with a sturdier construction...
