12/10 love this bed !

Love it thought it would've taken a while for it to pop up but it was fairly quick. My boyfriend is 6'6 and he loves it already cause his feet don't hang off 😂 overall it's a great bed.

I love this mattress!

I ordered two mattresses for my kids new bed frames. I was kind of skeptical at first because of the price but I read the reviews and with faith I ordered the two mattresses. Once they arrived in boxes I was already thinking not good but once I unboxed it and let it take its form and my kids were already bouncing on the mattresses. They loved it! The last mattresses were flat and not enough cushion. They hated those mattresses but THESE are very bouncy as my son says but it comfortable and they enjoy their sleep get to sleep quicker. I love it!!
