Best investment my husband and I have ever made! I was really nervous about making this purchase since it's not always a great idea to buy something like this without having seen/felt it. I'm glad I did though, it's been well worth it! We've had the bed a few weeks now and here is what I can say about my experience so far: Shipping was more than reasonable and MUCH quicker than I had expected. All 4 packages shipped together and even if they hadn't, I wouldn't have minded. Quick and easy removal and assembly. Definitely recommend airing out the pieces a couple of days because of the smell, but once you start using the mattress it's not noticeable. My husband is over 6ft tall so the extra length is definitely appreciated. Both of us noticeably feel very well rested when we wake up in the morning. I'm also VERY hot natured but haven't noticed a difference with this bed to any other bed I've had, but I also purchased a very good mattress cover, so I recommend you do as well. If that doesn't help then perhaps a pillow top cover will. I LOVE that we are able to adjust the firmness according to our comfort. I wouldn't mind a little firmer layer though. Make sure to buy deep pocket sheets, which you're more than likely going to have to purchase online. 72x84 is the typical size for a California King but this does say in the product description that it's 70x82, however it fits like a glove on our bed frame and the sheets fit perfectly as well. I would recommend this bed to anyone, it's a fantastic buy!
