A close relative of mine owns a furniture store so when it was time for me to buy a mattress I asked her what was good. She told me to check out Serta (specifically SERTA) memory foams. I liked them but found them too expensive in the store. I needed a mattress for my platform bed and I knew this fit the bill. I couldn't believe the price on overstock. I bought it while my friends laughed at me for buying something so important on line. I am very very happy I did. I was first concerned that 8 inches would be too thin. Somehow this mattress is very soft and very firm at the same time. I do not sink into it like a spring mattress and there are no pressure points causing tossing and turning. It literally molds to your body, warms up to your temperature and you are in a perfect mold of yourself for the night. Some mornings I wake up in the exact position I laid down in, perfectly rested. I'd even say I require less sleep because my sleep is so much better now. I had a pretty nice mattress before but this one is just amazing. Perfect for a platform bed! Shipping was cool, came on time, via UPS, in one big box, I cut open the bag, it inflated and I slept on it the first night. Pure awesomeness.
