Sturdy but needs a smooth floor

The build quality is solid and the foam padding is comfortable. Just make sure you use it on a very smooth surface; it slipped a bit on my textured bathroom mat, but works perfectly on the hardwood.

Great addition to my home gym

This sit-up assistant is exactly what I needed. The suction cups hold very well on my kitchen tile floor. It makes doing crunches much easier on my lower back since I don't have to hook my feet under the couch anymore.

Solid construction

The plastic feels thick and durable, not flimsy like some other cheap fitness gear I've bought. The foot hooks are wide enough to be comfortable even without shoes. Would recommend.

Good value, minor durability concern

It works as advertised for the price. However, after a month of daily use, one of the suction cups seems to be losing its grip slightly faster than before. Cleaning them before each use helps.

Perfect for beginners

I am just getting back into fitness after a long break. This device provides just enough support to help me complete my sets without straining. The three height adjustments are a nice touch for progression.

Compact and effective

Love that it doesn't take up any space when not in use. I just pop the suction cups off and slide it under the bed. It has definitely helped improve my core workout routine at home.
