We replaced our 10 year old sleep number with this bed. Prior to purchasing our Helix we tried a different brand that was just too firm so I was skeptical about the Helix, but knowing it had a sleep guarantee I didn’t hesitate and I’m glad I didn’t. The bed is exactly as advertised and does feel like sleeping in a cloud. The Luxe is worth the upgrade IMO. We decided to get the standard top, but wish that we would have gotten the cooling top as this bed does sleep a little warm, but I think we can mitigate that with a cooling mattress cover. The free pillows are awesome as well. We went with a split King because we have an adjustable base that adds to the awesomeness of the mattress. If you are a soft to medium sleeper this bed is an outstanding choice and you will not be disappointed. I highly recommend it!
