The flex mattress is extremely comfortable, and I like that it is not all memory foam. The mattress seemed really hot at first, but I changed the mattress cover I was using and have not had issues since. The pillows that come with the purchase are comfortable, but they are made of some slippery material so pillow cases will NOT stay on them at all. I likely will not use them anymore. I had ordered the platform as well, but ended up not using it. It is not returnable!!! The platform was very heavy but seemed sturdy.
