    Didn't really pay attention to the 6" when I ordered, but I guess you get what you pay for. Okay for my daughter's room until she grows a bit older.

    Good quality. It is a 6 inch mattress and therefore I did not have great expectations.

    For a six inch mattress, I have found it to be a good price, decent quality, comfy sleeping. We use it on a guest bed - and it has worked out well.

Questions & Answers

  • Q:

    "Why did you choose this product?"

    • A:

      because we needed a new bed frame & mattress

    • A:

      Good reviews, good price, good description. We purchased a different brand (I think) memory foam mattress a couple years ago and have been very pleased with it. This is for a guest bedroom.

  • Q:

    "Does this mattress come in a box, and what size?"

    • A:

      Thank you for your question, samijean21. Almost all of our memory foam mattresses come folded or roll in a vacuum sealed plastic bag. This mattress is for a full size bed. I hope this helps, thanks for shopping with us.

    • A:

      Yes it comes in maybe a 5 foot tall box that is thin

  • Q:

    "Does this mattress easily fold up? For instance, would it be suitable to be used as a futon mattress?"

    • A:

      Hello anonyma, This would not work well as a futon mattress. Thank you for shopping with us!

    • A:

      I don't think it would work for a futon due to the fact that it is very sturdy and I don't think it would fold easily.

  • Q:

    "Does this mattress use flame retardent chemicals?"

    • A:

      Hello mango90, thank you for your interest in the InnerSpace High Density 6-inch Full-size Foam Mattress. This product does have a flame retardant. It is made up of: The FR barrier we use is made up of rayon/basalt/cotton. Basalt is made from volcanic rock. The thread we use is a Kevlar /cotton mixture. Thank you for shopping with us and have a great day!

  • Q:

    "What is the ILD rating for the foam mattress?"

    • A:

      Thank you for your question. The ILD for all our foam mattresses is (34) with a density rating of 1.5 lbs.

  • Q:

    "Does this come in a queen size? I don't see this exact mattress on the website."

    • A:

      Thank you for your question. We do not have this specific mattress in a queen. I have attached a link that might help you. Have a great day!

  • Q:

    "How heavy is this product? I need to lift this up 3 floors."

    • A:

      When packaged, this product will weigh 27 pounds.

  • Q:

    "Would a 3/4 inch piece of plywood on top of a bed frame be enough support for this 6 inch foam mattress?"

    • A:

      If you use 3/4 inch thick OSB instead of plywood It's cheaper and stronger. That would be thick enough to support you on that span without any significant give or deflection.

  • Q:

    "How is the foam eco-friendly?"

    • A:

      Yes. The foam is eco-friendly.

  • Q:

    "does this product need a boxspring?"

    • A:

      Thank you for your interest. Mattresses require support. Memory foam mattresses are designed to work with a hard, flat surface such as a foundation, platform bed or bunky boards. Other acceptable support would be 3/4" plywood, a waterbed frame or other such surface. Memory foam is designed to do all the giving from the top down and putting your mattress on a boxed spring would defeat the purpose.

  • Q:

    "Does the mattress come with a box spring?"

    • A:

      Unfortunately no it does not.

  • Q:

    "What is the pound density of this mattress?"

    • A:

      This mattress is 2lb density.
