I wanted something that felt close to laying on plywood (sounds rough but it's actually been the best for my back). It's actually extra firm and is amazing for my back and neck issues. I fall asleep so fast and sleep so soundly. It's extra firm while also having enough "give" to not cause pressure points. Even if I have to end up replacing this every few years it's much more cost effective than replacing a whole mattress. Foam N More was great to work with; they shipped super fast and I received the mattress within a few days. It opened up and wasn't bumpy. It also had very little off-gasing smell which I was glad about! So glad I found this company!
If you're looking for a truly extra firm mattress/mattress pad, look no further.
