Yup! I got one and would certainly recommend it! It's pretty much my go-to onesie for sleeping since it's nice and warm, and I greatly enjoy the added thickness. And that's what I would recommend it for, thickness. The pad is plush, so really just makes it more difficult to walk normally than really waddle, but that can be remedied with some extra layers. Having the zipper on the back makes it a little more difficult to get into and out of, but it's really not that big of a deal as long as you can reach behind your back. Overall I think it's the best onesie I have, but that's just personal opinion.
Also, if you do purchase one be sure you purchase based on your measurements and not the sizes because I'm usually a medium to large and got a small that fits perfectly. Hope this helps!
