Received in a week from AZ to NY in a manageable size box weight 55 lbs. I got the twin medium firmness. Decompressed mattress in seconds on top of bed, no odor at all, full height measured 10.88" plus plush bamboo top. Slept on it same night, so comfortable with firm support and a bit of soft top. Great combo. The bottom high density foam is much harder for better support to the entire mattress.
Give it a few days, the real feel of medium firm latex will loosen up a little. It became a bit softer yet supportive, just what I was hoping for. After 2 weeks sleeping, this mattress delivers deep restful nights. No complaints, love it. Only time can tell how long it last.
