i was very apprehensive about buying a mattress set by web. but the serenity mattress is the best. set it up and slept for 14 hours. now as far as the delivery. i read all these glowing delivery remarks about how they set up the new one and took the old one away. NOT! we had a very short 130 lb driver who told us it was curb side delivery only. my husband and i helped him get the mattress in the house and set it up. as he volunteered to help us we tipped him very nicely. If you are older and can not wrestle a very large (19 inch) mattress and then the box spring after taking out your own box springs and mattress you may want to hire someone to come and help you out. it was a very hard task and my husband's and my back is much the worse for the savings. it was worth it however when you consider retail price runs 4-7 thousand dollars.
