Query: much better than my conventional mattress!

I had one of these before but my daughter got sick and well...we are not going to share details. I had to throw it away..so I ordered it from Amazon.com and was expecting it to be at my house within a few days. UPS lost the box, so I emailed Amazon, they rushed me another one right away! I never did get the other box but this product is wonderful!! My back is saying ahhhhhh again. When you open the box, you think, how in the world is this ever going to fit on the my bed but once the air hits it and it relaxes, it is true to size, easy to work with and wonderfully comfortable. I would highly recommend this product to everyone and the pillows are GREAT!!! They come INSIDE the cover not on the outside of the product. Best wishes and sweet dreams!
