Treela Foam Pit Blocks, Foam Gym Cubes, 4 x 4 x 4 in Protective Trampoline Padding for Gymnastics, Parkour Courses, Trampoline Arenas, BMX

These foam blocks come in various different sizes and colors. I needed something to fill a gap and they worked perfectly!! Literally hundreds of uses!!

These worked excellent for our foam pit at our gym!

These are not the advertised size! They are supposed to be 4x4 inches and they are a quarter of an inch smaller on all sides, which makes a difference!

Perfect size for ball pit!

these are smaller than a normal gymnastics gym block but work well for in home "ball pits" if you're looking to replace the plastic balls. Might just need to order more than you think

Good product. All expanded to a good size. Kids love stacking and playing. These are just foam so easily collect dog hair etc.

Smaller than expected. But they are ok.

Great for sealing up my garage vent hole. Would buy again.

My son is happy with them overall but about 20% of the blocks didn't expand right away. They took a fair bit of effort and still aren't perfect.

25-50% of the foam blocks did not expand. I pulled them apart a bit but not fully expanded.
