Nice Bed! Fast shipping! Large 125lb box! definitely need some help moving it into position!  came in vacuum bag and took about 20mins to come to life! i gave it a good 4hrs though. No off gassing! The bed is soft and comfortable not totally enveloping/drowning like other foam mattresses. I believe the cooling technology is the real deal bc I'll typically wake up in the middle of the night with the "big blanket on" sweating on the old mattress and this hasn't happened! Gave this 4stars only for motion, notice more activity/motion from the spouse moving, wasn't excessive though.
