I have the12” Queen size on the “Suzanne Metal and Wood Platform Frame,” also from Zinus. I’ve been sleeping on this baby for a month now and it literally feels amazing! I have an issue with hip and shoulder pressure points when I sleep so I’m constantly rolling over from side to side all night. Not with this baby! It sprang to life in about 4 hours after removing the plastic. I went to bed on this and slept for 10 hours... through 2 of my morning alarms and all! Would definitely purchase again!
