    The FLEXAPEDIC by Sleep Philosophy 12 inch Gel Memory Foam Mattress Maximum Comfort with Removable Knitted Cooling Cover will keep your body cool and comfortable all year round. This mattress gives you a perfectly balanced sleep environment—the right temperature, comfort and support. The 12 inch gel memory foam mattress has three different layers specially designed to give you the ultimate sleep experience. The mattress starts with a top layer of 2 inch of gel infused memory foam for comfort, support, pressure relief and improved airflow. To create gel memory foam, gel beads are infused into traditional memory foam. These gel beads add a layer of support within the foam, gathering together at pressure points to deliver the maximum support you’ll need, exactly where you need it. The middle layer is 2 inch of slightly lighter memory foam that helps to alleviate pressure points and acts a little like shock absorbers between you and the 8 inch high density base. You’ll find that you’re tossing and turning less and sleeping longer without disruption. The base is specially designed to prevent motion transfer, allowing you to move without disturbing your bed mate. The mattress has a specially designed knitted fabric top that’s cool to the touch. It also has a non-skid backing to ensure that your mattress stays put on a box spring or platform. Memory foam is naturally antimicrobial and resistant to allergens, mold, bacteria, and dust mites. TIP: Remove mattress from packaging as soon as possible (ideally within 72 hours of receipt) to maximize memory foam expansion. The mattress arrives tightly packed. Unwrap and allow up to 48 hours for this mattress to return to its original shape. Mattress is sealed in plastic packaging which sometimes traps odors. After unwrapping, please allow mattress to air for a few hours.

      Purchased this mattress for my 89 year old mother-in-law who lives with us. It is firm but flexible and she sleeps well on it. Came well packaged and immediately expanded to about 11 inches. Was delivered on time on the estimated delivery date given at time of purchase.

    • Best mattress ever!

      My mattress arrived few moments ago. And, I just opened it up and it immediately barely even took a few seconds before it blew up completely that was fast. So I'm laying in it right now as I'm typing .for the first time, I tossed my original mattess to the side. And.... all I can say is I'm falling asleep right right now. I'm going to bed i made my decision. Well Thanks for reading my review lol it's amazing mattress absolutely.

    Questions & Answers

    • Q:

      "Why did you choose this product?"

      • A:

        I was looking for the cheapest mattress that was on sale for 75% off. And I saw this was slashed down from over $900 the original price so I knew there and then this is a luxurious mattress for only over $200. My current mattress is 15 to around 16 years old. I had no plans to buy anything today, until I received an email from overstock saying they had over 75% off mattresses
