good advice. I got mine at Costco. It is a Hugo. I did not even realize there were rollators with plastic wheels. Costco sells a different brand now but DH said he saw the Hugo brand at Sam's Club.
Then again, I do not know if either Costco or Sam's Club is in your area.
I like the padded seat and compartment under the seat. It allows me to put my purse and bottled water inside.
My Hugo is pretty beat up now. I am looking to go to a medical supply store for one to use exclusively inside the house to keep the dirt level at a minimum on the carpeted bedroom.
Plus, skinnier is better in the house.
But Kitt, good advice.
