Fits a caldera utopia spa 89"x89" . We recently purchased a new spa lid, which was $500 dollars, hopefully this thin cover for our 2" thick foam cover will allow it to last longer than the last two. The california sun is brutal. It fit really well, and has pull strings on two sides to snug it up a bit. It might stay put in high winds, because it rolls down the sides about a foot! Very satisfied with the thickness of the material, the seams, and thread used. Seems very well made! Would order similar covers from this company for patio furniture or bbq in the future.

lasted less than a year. Too lightweight for the UV at high altitude. Totally fell apart

Great way to extend our hot tub cover. Keeping the sun on this easier to replace cover is a great way to protect our investment.

At first I thought the product was great....but now it's been a year, and the fabric has started to get super thin and rip. It is actually stuck to our new Hot Tub Cover that we purchased and then purchased this to PROTECT the Hot tub cover and it's not doing the job. I don't think it will last another 6 months. Very disappointed

Fit perfectly and it lasted through the winter! Still looks great!
