Was not as firm as I expected but it wasn't super soft! I love it! Family came by to see it and give it a try and we all think it's a great buy! Just had a baby so this new bed has literally changed my life and gotten rid of my back pain! Thinking of getting this for my kids as well!

one of the best mattresses i have ever slept on. when i say i fall asleep within minutes of laying down on it. was skeptical about buying a mattress in a box but this has proven me wrong.
