    • decent mattress for price

      Was easy to transport, as it came all rolled up. Puffed up nicely, and is comfortable.

    • Just what I wanted!!

      Got this for my teenage son. He loves it! Came rolled up in plastic and reinflated just fine as per the instructions. The cover is soft and seems to be of a very good quality fabric. I already own a California king of the inner space brand that is over 12 years old and still like new. These beds are awesome!

    • Perfect for the kids!

      Bought a twin and full size of this mattress for my son's wooden plank bunk bed. They have worked out perfectly. I LOVE that these are made in the USA. Made me feel good about my purchase. They are firm enough for support but soft enough to feel comfortable. Easy set-up and look very nice. You just can't beat this price for these mattresses!

    • My First Foam Mattress, I love It

      This mattress is a great deal and it is very comfortable. I'm a college student so I was looking for the best deal possible and this is the best one I found. I was a little nervous because I had never slept on a foam mattress before and I didn't know if I would like it. When it showed up my friends told me I was an idiot for ordering a mattress online that came rolled up in a box. But I tried it out, and they all agree too, this thing is awesome. There is no uncomfortable pressure of any kind when you lay on it. And you don't feel like you're sinking in at all either.

    • Bad for back

      I have had this mattress for less than a month and it has already begun to sag in the middle. I would recommend it as a guest mattress but not for long term use.

    • comfortable

      Ordered this mattress to go on guest bed that is like a platform bed but has a metal base so does not need a box spring. My mom stays with me part of the year and she says it is a very comfortable bed.

    • Great mattress for the price!

      Mattress is great, and perfectly priced. I received this for a spare bedroom. Although I cannot say for certain that I would sleep on this permanetly, it is great for a guest, child, or spare bedroom. Pretty darn comfortable too, especially considering when I first pulled it out of the box, I was a bit concerned with the size. Nevertheless, I am impressed thus far!

    • Good mattress for the price

      Firm mattress, I thought it was almost too firm when I initially sat on it, but it is for my 2 yr old daughter, so I like that when she jumps on it, she does not bounce all over the place. She seems happy and SAFE. Overall, a nice "starter" mattress for my daughter.

    Questions & Answers

    Get your product questions answered right here.
    • Why did you choose this product?

      • because we needed a new bed frame & mattress

      • 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.

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

      • 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.

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

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

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

      • 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.

    • Does this mattress use flame retardent chemicals?

      • 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!

    • What is the ILD rating for the foam mattress?

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

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

      • 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!

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

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

      • 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.

    • How is the foam eco-friendly?

    • does this product need a boxspring?

      • 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.

    • Does the mattress come with a box spring?

    • What is the pound density of this mattress?
