Nothing like this in the market at this price and quality.

Worth every penny spent fits nicely on to my current bed frame.

very nice bed

The 14" split king mattress is very comfortable and the adjustable frame works flawlessly. My wife and I love it in 2 weeks of sleeping on it. We used the golden glove shipping, which was worthwhile because they took away the old mattress and setup the beds and took away the packaging. The only negative so far is that we could not find instructions for the adjustable frame. Perhaps the installers threw them away. When I asked Zzen Sleep for a pdf copy or some guidance on some features, they asked us to call another party or company for support. I didn't think that wasn't super helpful. I still haven't done that as its a hassle.

One of my best decisions yet! I purchased the zero clearance adjustable frame to fit inside of my Cal King platform bed. It’s fits perfectly. My husband loves it too, as he is always writing when I’m asleep. For us to have our own adjustable platform is priceless.

Very comfortable bed.

I love my zero clearance adjustable frame bed. Very comfortable, quiet motor, amazing massage and position functions. I didn't expect it to be so comfortable.
