I received this product and was excited to test this out.  After sleeping on it for ~ 1 1/2 month, I can provide an honest review.  This mattress has an extremely firm structure on the outside which prevents it from losing form on the inner part of the mattress. The mattress is the perfect balance of firmness and plushness and is easy to get in and out of.  The 11" plush topper gives your body relief where it is most needed and reduces the movement when sleeping with another person.  I highly recommend purchasing this product!
