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.

THESE CHROME FOG LIGHT BEZELS-OEM MOPAR REPLACE PART FOR MY 2011 JEEP GRAND CHEROKEE REALLY MAKES MY JEEP STAND OUT IN THE CROWD

Plenty of valuable information. An absolute must have for the unfolding disasters in New Mexico, Hanford and Fukushima. The nightmare that just keeps on giving.

I have owned multiples of this and I do love it. The only bad thing I have to say about it is that the last 2 I purchased, once the battery that they provide you with runs out it never works again with a new battery. I am replacing the one I had right now since I have tried 3 new batteries and it won't work. If I put the old battery in that it came with it does work but is almost completely run out.

I didn't even know that Waterpik devices were still around, but when I recently started orthodontic treatment as an adult, it was highly recommended that I use a Waterpik daily. Nowadays I tend to look on Amazon first for anything I need, and I shouldn't have been surprised to find Waterpik units here. This one appeared to be at or near the top of the line, and seemed like just the ticket. It also appears that the company has incorporated a number of nice improvements over the years, and I think it's worth getting this high-end model to take advantage of them.
