I had been sleeping on an old, lumpy futon mattress that left me feeling bruised and aching every morning. When this first arrived, I was surprised how pillowy it was, but relieved to be sleeping on something soft for a change. Since then, my partner and I have noticed it has somehow grown even squishier and less supportive. We sink into the middle and have trouble getting up, and our backs ache all day. There is absolutely no firmness left to it after three months. It's also absolutely terrible for the other things one likes to do in a bed.
