## Questions & Answers

**Q: Is this washable?**
A: The exterior velvet cover is zipped and can be easily removed and washed. If the memory foam core also gets some stains, a wet cloth can be used to spot cleanse it, then leave it dry. Due to high density of the memory foam, please don't soak the core in water or other liquid though, as it will take too long for the water trapped in the foam to evaporate. Thanks for asking and happy shopping! - Sleep Science Customer Service

**Q: What are the dimensions for this pillow?**
A: Dear, the dimension for this lumbar pillow is 18" tall, 18"wide, and 5"thick. Much larger than many other pillows. Hope this helps. Thanks very much for asking!

**Q: Is this pillow good for a home chair?**
A: I use this pillow in my recliner. The big plus for me is: the width of this pillow is as wide as the seat 18" so stays where you put it. My previous pillow(s) were not as wide and were constantly shifting to the side. How annoying!  Otherwise no more comfortable than others I have owned.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Excellent product!
*by K***N on August 1, 2017*

I bought a different lumbar pillow and it was too small and hurt my back. I am a plus size woman 18/20 and this pillow fit my recliner perfect and gave my back the support I needed. Any pillow smaller than this on here are made for petite people. I had a lower lumbar fusion done and need the extra support and it's hard to find a comfortable fit. The higher back makes this pillow fit comfortably on the mid back and you don't notice a change between where the pillow ends and where the seat begins, which was important in choosing the right pillow. I use this in my recliner and it just feels like part of the chair itself. It looks exactly as pictured and is firm enough to give you all the support you need, yet soft enough that it allows you to conform into it. I highly recommend this product and will buy it again if I need another one. Worth the money! I just wish they offered it in black and other colors.

### ⭐⭐⭐⭐⭐ I love it! I brought it to work and placed ...
*by A***R on December 8, 2016*

I love it! I brought it to work and placed it in my office chair. It helped support my back. It is firm and very comfortable. I drove to my parents' house this Thanksgiving. I put it in the driver's seat of the car, it made the 3-hour drive much more comfortable. I highly recommend this!

### ⭐⭐⭐⭐⭐ Glad to find this one
*by A***R on November 9, 2016*

Everyday I commute 40-50 minutes to work. When getting older I feel that I really need a lumbar support especially for my lower back. Glad to find this one. The contour of this cushion aligns to the seat of my minivan perfectly. The memory foam is very firm and strong to support my back. Now I don't feel the stress during driving any more. Highly recommended!
