Appears to be some type of composite or maybe fiberglass for the cross bars and aluminum for the brackets. They install easily although take your time as there is a front and back and left and right. I replaces the provided screws with socket head screws.

I'm not exactly sure what it's made of, but it's fabric. Kind of a stiff sturdy felt.

It's made out of a covered cardboard material. Ours is pretty durable, and has lasted a year, but it doesn't take any abuse.

It appears to be made of some man-made solid material. I assume it is plastic.

It's metal, actually made of aluminum. It's really lightweight stuff. No too bulky and works very well. :-)

It is made from some type of cedar. We put a couple of coats of urethane on it.

The gel! It's made out of something that stays cool. There may be a more technical answer somewhere else.

It is made of plastic, but it's a very durable, thick plastic and I've had no problems with it at all.

This is made of a hard durable plastic. I have had mine for 2 years now and still look like new. I bought 8 of them.

I honestly don't know what it is made of? It feels like some kind of synthetic material, like nylon??? I can tell you it works great!

Don't know the material it's made of. But, unlike some who answered, the one we purchased was google looking, sturdy, and has served us well now for over a year.
