What is a quality and affordable brand of lift chair?

Chairs need to be fitted by height and weight, so she/he can easily step back and have the seat meet the butt, and get good lift. Some recline, some don't. If the seat is too deep, she won't be comfortable. If she has dementia, she may not be able to operate the controls.

Everything Pam says. My mom (and dad) have had La-Z-Boy lift chairs (mom's on #2). I can't say that they fit her really well. She needs a shorter seat, so she's not half lying down when she's sitting. If I had it to do over again, I'd try to get her fitted for one like Pam suggests. When her old one broke, I was in a panic to get her a new one, so went back to La-Z-Boy, where they had them in stock.

Now she half forgets that it can stand her up and she's getting weak enough that her efforts to stand up on her own are beneficial (to keep her thighs strong), so I don't keep reminding her. And the "Up/Down" control labels were confusing to her, so I made paper labels that said, "Stand Up/Sit Down" to help her know which is which. Both of mom's chairs eventually have a seat that gets lumpy (and we have to put a cushion on it). Recently her new chair (8 months old) broke down, so I had to pay $109 for a repairman to come and fix it. Luckily he was able to replace a couple of motors and fixed it without more waiting for parts. So also check their warranty and repair details before buying. Usually if you need a lift chair, if it breaks, it's a big deal and you need it fixed pretty quickly.
