Lucid Comfort Collection 3" Gel Memory Foam Topper with Cover, Twin

I bought this mattress back in May 2021, so I've had time to give well thought review. After only 2 months It began to sag on my husbands. He is prox 200lbs give or take a few lbs. We turned the mattress around to have the foot at head; It now sags too. My husband works 2 full time jobs and I'm disabled and neither of us gets a good rest because he has to sleep in the middle which is pushing me nearly off the bed Unfortunately, only 30 day warranty. No extra plan was offered and now I know why.
