Overall I love this mattress I would not hesitate the recommend this mattress in a box especially with Wayfairs return policy. 

Only reason I didn’t give this 5 stars is based off of some of the specs. I wouldn’t call this mattress medium, to myself and my husband we both agree it’s more of a firm-medium. That being said it is still very comfortable once we’ve adjusted to it. I also don’t find this to be cooling at all but that wasn’t a feature that was a deal breaker. 

This mattress does do a great job with not feeling partner movement, both my husband and I have noticed that we don’t distrub each other when shifting positions. 

We purchased a King sized and you will definitely need two people to handle it once you start unboxing and opening up the mattress as it expands quickly. It did not take long to expand itself and we noticed no odor. All and all very happy with our purchase.
