This mattress is extremely soft but has firmed up some over the last month. Overall I'm pretty happy with it. It is actually quite short for a standard full size bedframe. If I didn't have a cushion at the foot of the bed I would probably be losing pillows. As it is, the mattress has stayed in place and it is far more comfortable than the last mattress I had. That said, I would probably get the firmer mattress next time.
