I hate going to a mattress store to figure out what kind of mattress i need. I will lay on the beds and they feel great because you only lay on them a little bit. I want a bed that is soft but still moves with me to support my back. I went with memory foam mattress with the gel inside and it is amazing. I was worried the mattress wouldn't expand nicely with it being shipped in a box. No need to worry, it expanded perfectly. There was no smell on the mattress. This is a great mattress for a great value!!
