My daughter who is a X-fit athlete says the mat is too hard. As for me, I had no reference, I find the mat to be OK. Use it daily (or rather nightly) to do 100 sit-ups before going to bed!

Purchased this with 20lb ball and glad I did. I think it helps support lower back for safer exercise routine. That's my feedback!

I am 260 pounds. This gives me a little comfort with pressure point. I recommend this for anyone who needs a little push for crunches. It really gives u little ump. More energy more comfort. You can also do stretching and palate. Over all a trendy item.

It saves the tailbone from bruising, and the thick part is excellent support for kneeling exercises on weak knees. Feels firmer than other mats but it feels like it will last longer. I think it could be a little wider.

I was trying to do sit ups on tile floor and was experiencing a lot of pain in my back and tailbone. I got this and it really helps. Still occasionally feel a little pain but this is really helpful

Great product overall but it’s very stiff! I understand you want it to be firm but it’s to firm that it hurts my back. Material is not breathable, causing excess sweating during use.

Mat is much firmer than any other I have used.The tailbone protecting pad is attached on the thinner edge of the mat, so this won’t help prevent crack burn for most Crossfitters.

I purchased this under the impression that it was a general purpose exercise mat that provided tailbone protection. It's not. It's intended expressly for situps. I returned it.

This is a value purchase and I recommend it. The price point was too good to pass up for me. I've used a more expensive ab mat and can tell you it's more comfortable than this one. The Yes4All mat pushes up more on my back. It appears to be a little too tall. Besides comfort, it adds a little strain to the sit up.The Yes4All isn't as good as a premium ab mat but still worth the purchase. Personally, I just can't spend a lot of money on an ab mat so I'm happy with this one. It is effective but…

Just laying on this thing sometimes makes you lower back feels so good You don't even want to do the sit up or leg raise. It's a good buy
