No complaints. We've had it about 3 weeks and I haven't slept this well in a while since I was sleeping on my mils old bed for a year. My spouse and 3 dogs love it too. It's not too hard or too soft. My wife had back surgery two years ago so she needed something comfortable. She has not been in pain since sleeping on this. We also both have fibromyalgia and sometimes it is hard to get comfortable but that's not an issue with this matress either.
