Thickest Hot Tub Covers: 6"-4" Tapered with 1.0# (R23.85-R37) $488.88
Product Review (submitted on January 9, 2015):
I did a lot of research before ordering a new Hot Tub cover online. Some of the reviews for other vendors had real horror stories. I was favorably impressed with the reviews for Beyond Nice, but was still a bit apprehensive as to the result. The cover came a couple of days later than estimated, but it was the week of Christmas. It was undamaged, and exactly as advertised. It fits perfectly and I have noticed that the heater is running less. Can't comment on its durability but it looks to be a great cover!
