## Questions & Answers

**Q: Does this pillow go flat after a while ?**
A: In the beginning, no. I believe I used my pillow for about a month before I started to need to shake it some at night, which I do nightly now. I also take off the bamboo cover once per week when I launder the bedding and put the pillow in the dryer on "fluff" setting for 20-25 minutes. I have had my pillow for 5 months now. I still have the additional bag of fill provided at the time of purchase, but haven't needed to use it.

**Q: Can I purchase more stuffing for the  travel pillow?**
A: We do offer this on our official store. Not currently available on Amazon.

**Q: Where is it made?**
A: I have Queen size says made in China

**Q: Does the travel pillow have a pillow cases like the queen has?**
A: Our travel pillow has a removable washable cover at the moment.
We are just finishing up additional cases that will be available in about 3-4 weeks from today

The cases will be the same as the Queens. Fitted with zips also for easy access and easy washing
Hope this helps out. Reach out to us anytime if you need any help
