Are the casters rubber or plastic?

Hard plastic. Mine has been dropped and used by t.oddlers and small kids (my 10 yr old) for several years now and hasn't suffered more than cosmetically

Wheels are plastic. It took my husband about an hour to assemble. Instructions are easy to follow.

They are plastic, also the mold left sharp edges on the rim and I had to sand them smooth.

It is probably plastic, but it's very hard plastic and good quality. It's not bendable so guess it's NOT rubber! :-) The kids love them!

They are a hard plastic. Been using for a few months and seem to be pretty decent quality. The blender still rocks!

The wheels are plastic, but it seemed to go very well in the house. Haven't tried it outside on concrete yet.

Not sure. They are apparently hard plastic, not rubberized. My chair is on a carpet. It is a wonderful chair!

They are plastic but very durable... My 2 yr old has thrown them on multiple occasions and they are still going strong after 6 months

The wheels (rims) are steel, while the tires mounted on the steel rims are rubber. Very nice quality!

They are plastic, but a softer kind of plastic. At first I was disappointed, but my daughter has been riding it daily on concrete & asphalt for months, & it still works great.

They are plastic. We were hesitant about buying it for this reason, but my son uses it for almost an hour every day and they haven't worn out in the 4 months he's been using it. It is a bit loud, would be quieter if it had rubber wheels.

I believe that they were rubber, but the bolt mechanism rusted through within 6 months so I no longer have it. Not a good product, as far as I'm concerned.

I'm pretty sure it's plastic. I've had them for a long time now and I really like them though. They're decently made and pretty durable

They are plastic, but they seem to be pretty darn strong. I haven't had an issue out of mine yet, and I'm pretty hard on 'em.

The caster wheels are plastic, probably for easier rolling. The stem is 13/16". Hope this helps.

They are plastic..light weight but gets the job done FAST. Durable and handy, I keep mine hanging on a nail in the garage, so they are ready to go.

Katherine - truthfully, I am not really sure of the difference. What I do know is that they are composed of polyurethane or hard rubber wrapped around a polyurethane core. There is an axle and 2 of them have a locking mechanism which seems very sturdy. I've yet to have one of these suckers lock up and they make the rack marvelously maneuverable. I want to call them casters but all I care about is that they work.
