Simmons base - poor quality fabric

I bought a Simmons mattress Black Friday 2022. Was advised by the store that I had to purchase the base as well for guarantee and warranty purposes. So I did, even though the previous base which was a Serta was still perfect. On delivery I already noticed that the new Simmons base material / fabric was really loosely woven and just did not appear of high quality. My suspicion was confirmed … when Recently we noticed the fabric on one side is simply disintegrating. I went back to the store (Bed Centre Woodlands) as I’m concerned that the disintegration of the base fabric will impact my mattress warrantee. The store could not assist in this matter but instead sold me a base cover/ wrap and advised that I might have to buy a whole new base as Simmons have brought out a new base with better material. This I feel is ridiculous as my base is barely 2 years old. We bought Simmons for the main reason as it’s highly prized for its quality but I see now that this was unfortunately a very expensive mistake , which I will not advise nor support anyone to take in the future.
