The best!
This mattress is my absolute favorite. Not only do I long to be back in my bed every time I'm traveling, everyone who visits me, wants details on my mattress. I've had 3 family members buy one after visiting.

Best Mattress Ever
I got this mattress because it got a great review from consumer reports at an excellent price, but now that I have it, I have to say it's the most comfortable mattress I've ever slept on in my entire life, and I'm 53, and I'm a side sleeper, so that's saying something.

The Comfiest Mattress Ever!
This is the second time I've purchased this mattress over the years, and I'll probably buy a third. It's incredibly comfortable – just firm enough, but not too firm, and it's great for people who are side sleepers. I got one several years ago for my queen-sized bed, and I just bought a king-size for my son and his wife for their new home. I'll most likely replace my current king-size mattress with this one in the near future because it's the most comfortable mattress I've ever slept on! Highly recommend!
