      Very disappointed

      After three months the mattress is sagging on the side close to 2 1/2 "causing me to almost fall out of bed twice! At first I really liked this mattress until it started sagging.

      Great

      Great size but it’s too firm for a pillow top

      Very Comfy And Relaxing!

      This mattress is super comfy and relaxing! Along with keeping your back healthy and feeling great the mattress provides great support for a nights restful sleep, without waking up to severe back pain from an old mattress. This is a great choice for those who want a comfortable, soft, and back supporting mattress that will ensure a great sleep!

      Firm at first

      First night and it's a little more firm than expected - hoping over time that'll change
