The base can not fold, it is sturdy! I like to put the ball side down and use the black flat top to balance for planks, push-ups, squats, etc

Its some sort of plastic and no, its not flexible. If it were I'd be afraid it would collapse when using it. The reason I have one is so I don't squat any more and I don't have to expose myself.

It's round. It come in two pieces. The top bar (round as well) that extends and the bottom "U piece with wheels that folds. We use allot of these on set and with all of the wear and tear we put on them, they hold up.

The top and sides are flexible. The felt is thick and doesn't confirm, it stays in the circular shape. Very durrable, quality product.

Is it flexible at all? I want to bend it around a gentle curve, maybe equivalent to a 10-foot diameter circle.

It's fairly rigid. I think I would constantly be attempting to assume the flat shape and wouldn't stay put well at a 90° angle. Otherwise great mattress. Second one I've purchased.

it is stranded, so yes it is very flexible. anything with a unweighted turn diameter of 1/2 inch should do fine.

We gave this to someone as a gift a few years ago and I think the base folded, but not 100% sure. I am sorry that I am no help, but can tell you that the person lives in a small apartment and it does not take up a lot of room.

Do you mean "rigid"? It is rigid, not flexible. I love it and am so happy that I purchased this. I have so much more peace of mind, not to mention the reduction of heat on my legs.

They have a rubbery consistency but they are very rigid. I wouldn't count on bending them very far

yes, it is very flexible. There is an outer cover with velcro so it will hold into place.

It's pretty flexible...my fridge is also curved and my board does stay put!

Simply grab the corners and twist. The flexible frame will fold up into a circle shape about 7 inches wide. It takes some practice but after a few tries, it should become really easy to do.

It's not floppy. It's firm, but will bend a little if it need to. It should work fine for you. I'm very happy making pancakes with it!

Flexible roll up style. You could create your own plywood base and use industrial glue to secure this to a hard base.

It is a rigid yet bendable plastic. The base is a ring that is not full closed. About 20% gap which. You use to forcefully clamp around a bar. It is not very sturdy, but works well as long as you have it against something... The dashboard for example

It's more like chip board. Not flexible but it can be broken if you try to bend them.
