Waste of money!!

We were excited to get a nice new mattress after sleeping on one that I had since childhood. But we soon found out we wasted our money! This mattress began to sag within a year of buying it. We are only four years in and it’s got pretty deep indentations where we sleep. The middle is super high and then it sags way down where my husband sleeps and also quite a bit where I sleep. We are not big people, so there’s no reason for a mattress to sag so much after only a few years. We put in a warranty claim which was denied, stating that the sags stills falls within manufacturer standards for “normal” body impressions. But after reading more online it sounds like this company made crappy products and won’t honor warranties and subsequently went under. Wish I had known before I wasted my money in this thing. Looking elsewhere for a new mattress and in the meantime we are sleeping like crap and waking up sore. Might as well sleep on the floor.
