Bambi Cisco Mattress Started Sagging Just One Month After Purchase

Approximately four months ago, I purchased a Bambi Cisco mattress from Ada Mobilya in downtown Bilecik. About one month after the purchase, I noticed a problem with sagging and compression on one side of the mattress. This issue is noticeable every time I use the mattress and causes me to wake up feeling tired in the morning. Since a friend of mine also uses the same mattress model and is very satisfied with it, I believe there is a genuine defect with my product.

So far, I have not contacted either Ada Mobilya or Bambi customer service. I am requesting a resolution to this problem through this platform for the first time. My mattress is still under warranty, and I paid for it in installments. Since I do not believe that repairing the product would be an adequate solution, I am requesting a replacement.

I kindly ask that this issue be resolved and that appropriate action be taken as soon as possible.
