Only reason I gave three stars is because the product is good. Our bed was scheduled for delivery on April 16,2021. The delivery was made an hour late by two men who could not properly communicate in English and who did not represent Sleep Number in a positive light. In addition to the mattress, we had bought the Flex Fit Adjustable Frame. The store salesperson told us the legs on the frame were adjustable from 6" to 11" but the delivery people insisted they were not adjustable. They left the mattress and frame in our garage and said they would come back another time. I called Customer Service, who explained how the legs were adjustable, and together we decided that a longer leg would work better and arranged with them to send us the 16" to 19" legs. I asked Customer Service not to allow the original delivery men to deliver to us again. The same men showed up on April 21st to install the bed. They argued with us about how the frame would fit and were generally disagreeable. Luckily, this bed should last us the rest of our lives because I would never go through again what we experienced with the Sleep Number delivery.
