I love the bed, it takes about 3 days getting use to it. The massage for head and foot is was what I didn't like, it bother me when I put it at setting 2 or 3, It makes a ugly noise. Other than that it is comfortable.
We purchased the split king and my only complaint is that the mattresses separate during the night leaving a gap that our little dog falls into. I worry that she could get squished.
We are happy with our decision to purchase the Matrix 3D bundle. The adjustable base has the position versatility we appreciate. The mattress is very comfortable and is providing us with some good sleeping! The sheets and pillows that came with the bundle are great as well. I was tentative to buy a mattress by mail, but it was easy to set up and the 100 night guarantee gave me peace of mind.
