I purchased this item 2 years ago and was very happy with it. It was easy to assemble and I have enjoyed using it. Last year I switched out the lava rocks for glass rocks as any moisture that accumulated over the winter in the lava made them burst. I used the cover that it came with continuously and feel I maintain the products well. Unfortunately as I uncovered it this spring, it has begun to deteriorate. It is supposed to be a concrete compound so I never expected that to happen. It is turning into an ash like substance. Also practically over night the cover has now disintegrate as well.
I called Wayfair and basically it's well past the 30 day return policy as well as the Manufacturer 1 year warranty. My suggestion would be to buy something else if you want it around for a while.
