## Questions & Answers

**Q: How many does it come in a box? The picture shows multiple which is confusing**
A: One to a box. I think the picture of three is just to show the different colors available.

**Q: I sleep in an upright position due to an upper respiratory problem. Will this help my lower back in a standard wing back chair?**
A: It may. It's very short, but long across. The bottom is much thicker than the top, so it doesn't exactly conform to the shape of my lower back. If you look at the pictures, it's pretty much exactly like that. You won't be able to use the strap in your chair, so it'll move around if you move. Maybe check auto parts stores for an actual lumbar cushion. I found one at Napa that's perfect.

**Q: Will this work for sitting in bed reading?**
A: You can use the cushion in bed if you sit more upright. The cushion is not suitable for laying.
If you sit more upright, pillow will support the lower part of the spine.

**Q: How much does ot weigh?**
A: It is very light.  I just looked on the product page, and it says the shipping weight is 1.1 pounds, so the actual product weight is probably less than one pound.
