## Questions & Answers

**Q: Does the foam have a strong chemical smell?**
A: I bought this item was a while ago, but the one I got had absolutely no odor to it.

**Q: How wide is it really? Please measure. Gives 2 different measurements. 3" by 15" by 14", and 3" by 18" by 14". 18" seems a bit wide for some chairs.**
A: We've measured the product the it's 18"W x 14"D x 1 1/2" - 3". The 18" measurement for the width is pretty standard for most wheelchairs. As for other seating surfaces, it would fit perfectly in most desk style chairs.

**Q: Is it good to use as a seat cushion at a concert (Hollywood Bowl)?**
A: This seat cushion is fantastic. I use it for everything but have not been to a concert. I see no reason that it would not work well at a concert.

**Q: Is this cushion too small for a lift chair/recliner?**
A: The cushion is 15.5 inches wide and 14 inches from front to back. My mother used one in her chair that was a lift chair/recliner. It's worth trying it as the cushion, for me personally, makes the limited time I can sit at least a comfortable experience.
