Review on Mattress Dimax Optima Premium 3, 120x200 cm, spring by Czesawa Wlazo ᠌

Some pros: Vacuum packaging of the mattress upon delivery (in a roll). The appearance of the new, the quality of sleep on the springs. Got cons: The mattress is six months from the date of purchase, and we slept on it for about 4 months in general, during which time it was turned over three times (recommended after 3 months), so the fabric and the material under it swelled at the location of the maximum body weight. and on both sides of the mattress. And the tag says 10 years of service for this mattress! GOST 19917-2022 really allows such quality? Who will refund my money for a product of inadequate quality?
