First I saw this thing in a magazine at the doctors office. Checked out the web page and was shocked at the price, $2800. WOW. So I went to work and built one for my self. Well it's for my daughter. For about $600, Custom 3 inch thick mattress, It's an 6 foot octagon shape with 6 ropes teathered to the celing. I have to say it's the most comfortable thing to sleap on. She says that she doesn't want any other bed and its been 5 years.
