I just bought a king size one last week. Nectar Ultra mattress, top of the line. It's very comfortable, we slept on a Casper the last five years. Couldn't get the base for it, they were back-ordered. I finally got two Purple single bases. I was able to pair them together so both work at the same time with the remote. Besides being able to raise the head and feet ends however you want, I have an anti-snore and "zero-G" options. We still sleep with the mattress completely flat since we are side sleepers. You have to buy some special brackets if you want to attach a headboard and footboard to the frame. I think all of the bases are basically the same Chinese made stuff. I didn't care to pay extra for the vibrating frame with lights under it with power ports. We had been sleeping on a queen for 40 years, so getting use to all the extra room is nice.
Thanks Dave
