  • Q:

    "is there a weight limit the person weight I weigh 400 lbs what do you recomend for me."

    • A:

      is 400 pounds to heavy for one of these mattresses?

    • A:

      Hello robert0730, I was able to find some info on the internet that stated consumers weighing over 400 pounds were happiest with a mattress between 10 and 14 inches thick, because of the extra support a thicker mattress provides. In my opinion i feel this would be a good option for you. I hope this helps. Thank you for shopping with us.
