My in-laws bought this with the smart max cover in October, it was given to my son the end of November and by January the front seam had split and little beans everywhere. We had a warranty replacement, and now  (June) that one has split in a different place. Little beans everywhere again. I don’t think our use is excessive, mostly playing video games.  My in-laws bought it and I really couldn’t  be bothered to put them through another return.
It was really comfortable and my son enjoyed the chair a lot.
