Total cost was $70, and it's the most comfortable I've ever slept. Two other related recommendations ... I've got all sheets from MyPillow, and find them to be extremely comfortable (and properly sized - no short-sheeting!), and the low-cost Bamboo brand pillows (which I got at SAMs) are amazing.
The stripe pattern sheets at MyPillow are recommended, as they help get the sheets on right the first time.
The Bamboo pillows are really god and last a long time too..
