Isokinetics has a few chair style types and I am not sure which to pick - which is better, the metal frame or the plastic one?

I have the metal and I like it. Green Glass Girl probably didn't read the instruction to slowly inflate the ball and let it rest. I've had NO problems with mine.

I can't compare as I never used the plastic frame, but the metal frame is great and holds up well.

I returned my chair due to the ball. The metal frame was flimsy and the ball did not inflate to the size it was supposed to be. In the end, the fully inflated ball dropped right through the frame and I had to fight to get a refund. They made me send pictures and accused me of not reading the instructions. Not worth the money at all!!!

I have the metal one - the backrest broke after about a year (40 hrs a week usage). I welded a brace on it but now that I see the plastic model I'd be considering that. Side note: mine arrived damaged, I had to ream out one of the leg holes to get the roller inserted.

Plastic frame with a metal slide. I've had one for years and still shoots great.

I have purchased both: this one is an all metal frame. Incredibly sturdy. The front tire is a real tire (think bike tire), which is the reason for needing to purchase a new one from the original one--the plastic tire(s) wore holes in all of them. I highly recommend this one for quality. For convenience, not as much, this is MUCH heavier. Can't just throw it in the back of the vehicle to take to grandmas house ;-)

I bought this one first and then the one with the metal. The one with the metal hinges is way better. You can take them out if you don't need as much support. The other also has more Velcro and stronger straps. Is definitely worth putting a little bit of money out for the other.

It's plastic but if you want metal the more expensive BDR-XU03 is magnesium and even slimmer.

I've had both. The newer model is more sturdy, heavier duty plastic parts, in general, a real improvement. Works the same, but I think it will last longer, I've had mine about a year now.

The legs are metal but foot rest is plastic. We use it to transport patients and have had no issues with the unit.

I have no idea...but I know that the Chico Polly vinyl is the best cuz you can easily clean it, has wheels so I can move it from one room to the other easily and it adjusts in height and it has 3 seating positions...I love it better than any other high chair I looked at! U can't go wrong prob with either I would assume.

I would have to agree w/ "CyberTom's" response as the one I own flexes a great deal. I would look into something w/ a steel/aluminum frame.

I ordered the metal support frame with mine, it works fine except the side legs are too close to the edge, very easy to stub your toes...and very painful.They really should have recesses the legs on the frame. I would think a regular box spring would work fine too.

Key parts are sturdy metal and others are plastic. We looked at several stores that sell stationary bikes. Which stores carry this model vary by location. Or try finding this model at a gym near where you live. We ordered via Amazon because no one else came close in price. It was not difficult to assemble and tools were included.

It's fabric, not plastic. Personally, I like that better because the old chair I had was vinyl/plastic and it cracked at the seams and stuff.

If you mean the seat base or cushion frame YES it is molded plastic. The lower part that the seat sits on is all metal. I've purchased several seats over the years and this one is very impressive. I don't think you'll be disappointed with it.

The frame is metal. The only plastic items are the hanging toys and the piece under the seat that holds the batteries.

The frame is metal. There is some plastic but I think it is to protect the joints not for support. So far 6 mo old likes it. We will see if it works for a toddler.

Both. The bulk of it is metal (the blue frame and the yellow parts). The red seats are plastic. The black handles are foam padding like handle bars on a bike.

The parts are metal - no plastic! We've had two chairs for almost a year and they're great.
