Serta Perfect Sleeper

So far so good. I do like it better than my previous mattress which was more of a soft pillow top firm plush mattress. It was too soft and my back would hurt a lot. So I’m hoping this firm sleeper will do wonders but so far it feels great

Sink hole

When I first got this replacement, it was great, and now, for the last four months I’ve been dealing with a sink hole and is killing my lower back.
