What product is considered the Rolls Royce of walkers for the elderly?

My mother has two rollators -- a bariatric model and a smaller one. When we go out to eat at our local cafeteria, we put her tray on the seat of the rollator. It is very stable, so no problem. The main thing you want to look for is good durability. The cheaper models have brakes that give out quickly and sub-seat baskets that come apart at the seams. Good brakes, a good seat, and handle bars that feel right to your mother are things to look for. Heavier models with a wider wheel base are the most stable. I don't know if any one company is better than the others. My mother has two Drive rollators -- one very good and the other not so much.

A word of advice about transporting food on a tray: a walker is not ideal for this; there's not enough stability on the handlebars and the tray must be perfectly balanced as it would generally attach to the walker only from the front, at the handlebars. Think in terms of a bicycle, without a basket.

Possibly you could find one that has an angled brace attached to the handlebars - like a cantilevered brace. That would provide more stability.

Walkers don't roll though, they're pushed, with a little bit more effort than is required to push a rollator.

Rollators are more sturdy, a meal could theoretically be transported in the basket beneath the seat, but they are unwieldly when being put into a car because the 4 wheels don't remain stable even when the rollator is braked.

We got one for my father through Medicare; I asked his ortho doctor for a script; he provided one and Medicare paid for it, entirely.

It wasn't a high end; I'm not sure if there are such things in the world of durable medical equipment rollators and walkers.

Just as important though is to get a walker and rollator specifically adjusted to your mother's height; otherwise, she could end up bending over.

I would suggest you make a checklist of features by searching online to find ones that have the most appropriate and needed features, then contact local DME suppliers to find out what they have.

My mother fell using her rollator.
She never went back to it. Preferred the light weight walker instead. The accident she had could have easily happened with the walker but she blamed the rollator. The walker was so light in comparison and easier for her to use. Only needed a change of new tennis balls for the front legs from time to time.
She didn't like her basket on the rollator because it kept her from getting close to her cabinets or microwave or lavatory. Maybe it was a problem with the one she had and wouldn't be the same for others. Just a consideration.

Get the doctor to write a script for one then head to a medical supply store. No charge. I think Medicare allows one every 5 years or so. The staff can assist in getting the proper one. My mom has a rollator. When she is tired, she can sit on it. The rollator has a basket under the seat which helps during grocery trips. I purchased a black velcro catch-all that is typically sold for baby strollers (Amazon) and attached on upper bar. Works great! Keeps small items and bottle or water secure when she is on the go.
P.S. It took a few lessons to learn braking technique.

Whether you go with a regular walker or a rollater, I would let her try them each out first to see what she feels more comfortable with. You might be able to borrow a couple for her to sample.

I'd also discourage her using it to transport food. I'd be concerned with safety issues, especially burns.

Just like buying cars you need to shop for the features you need and the style that appeals. It would be best to buy from a store where she can be properly fitted and able to try out a few different models, even seek advice from an occupational therapist. If you choose a rollator you need to consider things like her ability to use the brakes and remember to lock them before trying to sit down, the width and how well it will fit through doors and hallways (especially the bathroom). There are so many makes and models out there, and the "luxury" ones aren't necessarily any better than the more basic ones because they all have to meet the same safety standards.

I bought my Dad an Essential Rollator, which had the hand brakes, a basket, and a seat. Oh my gosh, Dad was like a teenager, you'd think I had bought him a Shelby Mustang he was so happy with that rollator. He had it with him at all times. He learned to use it pretty quickly as he had to learn the hand brakes on his old bicycle.

This rollator came in different bright colors. I got Dad a shiny blue color. I've also seen tone in bright red, the seats all remain black. It was expensive, about $150.00 as I was in a rush and took what the private store front pharmacy had on the floor. It probably can be bought cheaper elsewhere.

Dad wasn't very tall [shrunk over the years] so I was able to put the rollator right into the cargo bay of my Jeep without folding up the rollator... but it was heavy to lift up [I am a senior myself, can't lift things like I use to].

If you get a doctor's note, I think [not 100% positive] that Medicare will pay for it.

Good points about the weight and ease to get into the car, I know that the one my mother used was a huge pain to fold up as we had to remove the basket first.

I did a double take when I read that you considered your dad's walker to be expensive at $150, here that would be the starting price for a basic model ;0

My dad has a walker, decidedly low end, and a rollator, which is much nicer. He doesn't have a basket, but it has a seat with a foldable storage area under it, and he uses the seat to push around all kinds of things including a plate of food. We got a prescription from his doctor for the rollator and got it from a medical supply store. They fitted it for his size and height, put it together, and gave him "lessons" on its use. It didn't cost him anything between his insurance and Medicare. He likes the brake feature and I like that it's easy to fold and put in the car.

I had to use a walker several years ago when i had my hip replaced and found a cheap one at a garage sale that worked just fine for the short time I needed it. I was still strong and could move it easily and get round obstacles in the house.A few years later I brought a new rollator for $35 at a garage sale in anticipation of needing to use it some day. Well that day came sooner than I expected so I use it outside when going for my mandatory exercise. Very easy to use as it has four wheels and the brakes are handy when I want to sit and rest. I don't use it when I go out as i can walk short distances with a cane and use last summer i fell badly at my daughters house and couldn't weight bear for a few days so she went out and brought me a very nice walker that has wheels on the front. She would not let me pay for it so i have no idea of the cost but it is a pretty red color. Folds easily and is light weight and easy to fold and lift into the car. There are all kinds of trays and baskets and bags you can buy to put on any of these types.
I can still carry a cup in one hand but would use a travel mug and put it in the bag, some have holders for drinks. i probably would not transport a plate of food on the tray and don't need to worry about that as I can use a cane still and hold something in the other hand. If it was necessary would use a plastic plate with a snap on lid and carry it on the walker tray. All types of walkers can be adjusted for the height of the user. It might be worth asking the Dr for a PT assessment and have them help with the choice and height adjustment. Either that or an occupational therapist. these people will show you and your loved one how to use whatever is chosen properly and adjust the height.
As a side note I find the rubber tips on a cane slip on a wet floor or especially on ice. I am on the lookout for a spiked tip to put on the cane for the ice. In my case I can still drive and go shopping alone and find that there are frequently no handicapped slots available in parking lots especially at hospitals!!!!!!!!! It takes trial and error and of course co-operation from your loved one and know many are resistant to be seen outside with any kind of assistance aide. Personally I would rather do that and end up with a broken hip on the floor and have everyone see me being carted away by the EMTs. I do know how difficult it is to transition from being an active fairly healthy senior to having multiple health problems and accepting the fact that life has changed drastically and downsizing the tasks I can perform and transition to smaller hobby projects.
