Some of these are called nursing beds. There are manual and electric ones now. Grandpa is old and can’t get out of bed. I bought him a hand-cranked one at the medical equipment store of Baoshan Branch of Shanghai Huashan Hospital. , the same as those used in hospitals. When you go to buy it, it is best to measure the size of the bed at home, so that you are not afraid of buying a bigger one. You don’t have to worry about installation. The store will come to install it and teach you how to use it. The service is very good. They will call us in a few days to ask about our usage. The price is the same as online. I suggest you buy it in the store so that you can see the real product and feel more at ease
