Thickest Hot Tub Covers: 6"-4" Tapered with 1.0# (R23.85-R37)
Product Review (submitted on February 19, 2013):
This is probably the 4th cover we have ordered over the years and Beyond Nice was beyond great to work with. The cover fits perfectly. We upgraded the cover to the denser filling and it appears very strong. The only criticism was some difficulty using the internet form. Could be our computer but it was worth the phone calls to get our cover correct. We are Beyond Pleased.
