We purchased the split king mattress and adjustable frame set to replace our standard king mattress and box frame. The set came delivered in four large boxes. Two boxes each contained a twin XL foam mattress that was compressed, rolled ans sealed at the factory. They were heavy, but manageable by a single person. The other two boxes were considerably heavier and larger. It would be easier to move them with two people, but I was alone, so I pushed the box on the floor just fine. The two larger boxes each contained a twin XL adjustable frame, including instructions and all hardware to install the frame. Assembly was easy and took about 20-25 minutes, plus another 15 minutes to clean up and recycle all the plastic and cardboard.
I immediately unrolled and opened the mattresses to air them out. The mattresses have a good amount of weight to them and feel like mattresses costing twice as much. The quality of the fabric is excellent and feels very good . There were no noticeable blemishes or imperfections. There is a noticeable chemical odor from the gel/foam, but after a day, it was mostly gone. I allowed about 24-hours for the mattresses to decompress and air out. After 24-hours, I didn't see much movement from the mattresses so I proceeded to assemble the frames.
The build quality of the frames is very good. The frames are solid and the welds look clean. All the edges are smooth and the components all installed easily. Once assembled, the frame is sufficiently heavy and sturdy, with little to no movement. Our traditional wood sleigh bed frame fit snug around the adjustable frame. We had to remove the center wood supports to allow space for the adjustable frame to fit, but it looks clean and almost custom-fit.
The motors and lift mechanism are quiet and smooth. The remote controls are beefy and feel good in the hand. The mattresses fit neatly in the space and the height is perfect and very similar to our previous mattress with box spring. We are very happy with it so far.
We haven't slept in it yet, but have been laying in it most of the day and the firmness feels very comfortable. I'll try to update once we've slept on it for a few weeks.
