Hi Hallie06512,
As you probably know from your reading here they are a member of this site which means that I think very highly of them and that I believe they compete well with the best in the industry in terms of their quality, value, service, and transparency. Post #17 here has more of my thoughts about them as well.
Hopefully some of the members here that have dealt with them will see your post and share their comments but outside of the reply to your other post here … you can read some feedback about them here and here and here and here.
An exact phrase site search on Comfort Sleep Systems along with a forum search on comfortcss and on CSS (you can just click the links) will bring up all the other forum comments about them as well.
