Thickest Hot Tub Covers: 6"-4" Tapered with 1.0# (R23.85-R37)
Product Review (submitted on February 14, 2013):
This is my THIRD cover in 7 years, the factory one, the next, and now this one. I must say so far I'm very impressed. I ordered my second cover from my dealer and a few month after receiving it there appeared flaws...spoke with the dealer and no luck and over the next few years it became HEAVY, nasty, and lots of leaks.
So, it was time to buy another, looked at several online sites and found this one. The choice of options, free shipping, and site features were very impressive. After searching the site, measuring the tub, and placing the order my only negative would be I was a little anxious to if I had it right...I called several times and never got an answer. To be fair I didn't leave a message, when I called I was never in the place to receive a call back.
So, a few weeks in and I'm impressed, if not I'll post my review later if allowed to give a followup.
