High pressure... You have to flip in those (9 minutes) but you lay on a nice soft pad and the beds are awesome you will never burn. Spendy though, about 30 bux a tan.
before when i did use them though id go for the stand up one...when you lay down your back and ass tan darker where it touches the glass so unless your relly dark you look kinda fucked up..
I use medium pressures once a week, if I don't spend the weekend out in the sun. The max time you can lay in them is 12 minutes. I don't like having to flip over half way through my nap.
