Advice with walker for my mom.

Hello - my mom is obese and she also suffers with lymphodema. She fell this past Thursday pretty badly and has decided to start using a walker instead of a cane - mostly for safety reasons. She has changed her eating habits and is working towards losing weight (im not sure what she weights bc i don't want to ask her that and have her feel uncomfortable - but she is and has been taking steps to be healthier/more/mobile.)

Right now we have a regular walker but Is like to get her a walker with wheels and a seat. I think this would help her be more mobile. Also, I want the seat to be large enough so she is comfortable and doesn't feel like she is being cramed into a spot.

Does anyone have any recommendations for a high quality walker with a seat and wheels? I found one on Amazon for about 200$ but I want to read different reviews and advice from someone who might have used one before.
