## Questions & Answers

**Q: Is foam firm enough not to compress when I put under my back/buttox while exercising?**
A: Yes it is - foam very firm

**Q: Can I order a custom size?**
A: Hello, 

Thanks so much for reaching out. We do not offer custom sizes at the moment. What size would you like though? We can look into adding it as a separate product.

Thank you,

Phil

**Q: is this made of closed cell foam?**
A: Hello, this back cushion is made of open cell foam. Please let us know if you have any additional questions at all. Thank you, Phil

**Q: will this help a person who leans and favors a side in a wheelchair? I was thinking of putting the higher side where she's slouching to even her out.**
A: The wedge measures about 15 inches by 11 inches, so while it might help some I don't think the size would be an ideal fit.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great for lumbar!
*by D***C on September 16, 2024*

Its just the foam no cover. No problem. Not too soft just right. I ordered the small. The firmness orks great for back support.

### ⭐ OMG Hard as a rock
*by S***Y on February 29, 2024*

This is perfect if you want to sit on something hard as a cinder block. OMG is it ever hard. It was really painful to sit on.

### ⭐⭐⭐ Different than previous versions
*by I***Y on September 29, 2024*

I bought 2 of these in 2020 and they really helped me. They lift your tailbone enough, so that it prevents a lot of back issues that come from sitting in a flat chair.They have both lasted for a long time and I didn't feel the need to buy a new one until 2024. The new one I'm using has been a different experience. When I first put it on my chair and sat on it, it felt extremely firm. I assumed that this was normal and I just didn't remember how it felt in the beginning the last time I bought one of these (I mean, it was 4 years ago).I've been trying to break this wedge in for almost 2 months now. It is still very firm and I don't think it's helping me the way my previous wedge did. The extreme firmness of it gives me lower back pain, if I sit on it for too long.For reference, I weigh about a hundred pounds. Reading the reviews of this thing, I noticed a lot of the older reviews said it was "too soft" and now, some reviews are saying it is too firm. If the company changed the firmness of this wedge, here is my suggestion: offer 2 different wedges. There should be a firmer option and a softer option.
