I wasn't sure about buying a bed in a box or a bed that I hadn't tried first. I looked at many different beds and reviews, asked friends and coworkers, and came back a few times to Zinus. I have scoliosis and need good support from a mattress but also pressure relief. This mattress is the best sleep I have had in a long time. It has great support but also gives when I lay on my side. I don't wake up with an aching back. I don't want to get out of it when the alarm goes off! Neither does my pup. We are both delighted with our new bed!
