Was definitely a little hesitant buying a mattress online and one that comes in a box. I've only had box spring mattresses before so the memory foam was new for me. Was real easy to get out of the plastic wrap with the handy slicer they include with the mattress. Was amazed how quickly the mattress grew to full size. I personally let the mattress sit for 36 hours before sleeping on it. Great purchase so far, especially with it being under $400 with tax. 5/5 I highly recommend this mattress to anyone looking for an overall quality nights sleep.
