It's stable and sturdy. I'll share some facts and tips for those who are considering this unit. The outside dimension from side to side, including all pieces, is about 22.5 inches. At my house, that's narrow enough to roll into a bedroom but not a bathroom. It would just roll through the bathroom doorway if there was no door, but a standard hinged door gets in the way. The seat itself is about 12 inches square. The space between the uprights is 16.5 inches, so if you're any wider than that, it'll be a squeeze. Hand tightening the handles at the desired height worked okay for me, but a frail person would probably need some help. The usual guidance I've seen for walking aids is that the handles should rise to about the crease in your wrist. I'm 5'9", and I had to raise the handles to their highest stable position to reach my wrist. I've got the handles standing 36 inches off the floor. The product specs say they can go to 37", but I was leery of putting them any higher. If you're a six-footer, 37 inches might not be high enough anyway. The seat is 21" above the floor - not adjustable. The handles stand 14.5 inches above the seat, at the handle height I'm using. That might be good news for you if you'd need the support to stand up. It might be bad news if you don't like having high "armrests" when you're seated. The 7.5-inch wheels are pretty good at rolling over minor obstacles, but sooner or later you'll have to lift the unit. The product specs say it's 20 pounds. Think of it as something like a couple of gallons of a beverage, or a case of 24-ounce cans. If those are too heavy for you, the rollator is too heavy for you. The brakes work fine. Someone with weak grip strength might have trouble. You squeeze them bike-style to brake temporarily (without letting go). You push them down with your palms to lock the brakes so you can let go. The basket isn't described in the instructions, so it took me a few moments to puzzle it out. My instructions: Insert from the front ("front" meaning the direction you'd walk in), with the two hooks facing the rear. Rest the hooks on the crossbar where the seat hinges. There's a ridge in the bottom of the basket. Rest that on the forward lower crossbar. When it's in position, the seat partially blocks it from above when the seat is down. The raised seat reaches down into the rear portion of the basket. You'll need to remove the basket to fold up the rollator. There are a few other things to note about folding it up. First, the strap anchored to the crossbar is handy for starting the folding process. There's nothing to lock the rollator into a folded position. I find it's very eager to open back up again. I use an 18" bungee cord to hold the folded frame together. There's also nothing to hold the seat or backrest upright while the rollator is folded. For me, this is less of a concern than the frame opening up, but it'd still be nice if the whole thing folded up securely. It doesn't stand upright on its own in a folded position, even with a bungee cord on the frame. That's fine it it'll lie flat in a car trunk, but you'd need to prop it up against something otherwise. Another thing about folding is that you're pretty much stuck with lifting it when it's folded. Suppose you need to squeeze through a tight spot. You can't just roll it through opened up, so you fold it up with the intent of pushing it through sideways. Not gonna happen. The rear wheels don't turn left or right, so you're not going to be able to roll the unit sideways. Or suppose you want to push or pull the rollator forward while it's folded. That's not going to work either, because the front and rear wheels are going to rub against each other. You'd drag it more than roll it, so you're probably stuck with lifting it.
