First of all, these are amazing beds. They are especially great if the person that you sleep with likes a different mattress firmness. Most importantly, they are extremely comfortable.
The only drawback (as noted in Consumer Reports which also notes that these are top rated) is that they are slightly warm and retain heat. I sleep hot, but just keep the room slightly cooler and is fine.
Also, the store sales experience is extremely professional.
Lastly, I'm bothering to rate the store due to the great customer service. We had a mistake on our order from a year ago and didn't get shipped the SleepIQ (it actually tracks your heart rate and breathing to help monitor the quality of your sleep). Despite the 12 months gone by, they were perfectly happy to swap things out for us. They may charge a premium for their beds, but it is returned in quality and service.
