My husband and I have these Purple beds. We placed it on the base of our previous adjustable beds, and it works perfectly. We LOVE these beds. I am now able to sleep on my side without my hips or shoulders hurting and waking me up. They stay cool and never reflect back the heat like our previous Temperpedic beds did. Since you have a full 100 days to try it and if you don't like it, it is a full money back guarantee, there is nothing to lose. I wondered how they would handle that, but their website says that since it wouldn't be possible for you to repackage it in that original purple roll, they give you back your money and arrange for a charity in your local area to come pick up the bed. I HIGHLY recommend this bed. (And no, I don't work for the company, and I am not paid to say this! I just love the bed.) (Oh, by the way. If you happen to see some of the "self produced" people posting videos on You Tube telling you how to open and set up the bed, most I've seen are just plain BAD. First of all, it comes with INSTRUCTIONS. It has a special opener which slits the tube in about 2 seconds. Some people made it look impossibly hard to do. I am 72 and my husband is 66. We did these all by ourselves. Each Twin XL weighed 75lbs. We just used the handles and brought it into the bedroom. Lifted it onto the bed, and unrolled it. Simple. Don't be fooled by some of the videos on You Tube making it look hard or almost impossible.) (I am not a "verified purchaser" because I bought these twinXL directly from the company. But I really have no reason to lie about what I've said. Here is a portion of the email they sent me.

This firms up all connective tissue...including the tissue that lines your blood vessels. I am 42 yo woman who took this supplement for almost a year. Initially, I was pleased with the aesthetic firming that this supplement gave me. However; over time I started experiencing bursting blood vessels in my fingers.

It takes some getting used to with really curly hair, I get it tangled once in a while (the hair kinda wraps around it even though you are starting on the ends and working up) I will see how it does when I get used to it, it's made well and very attractive.
