The Star Dust Chair was one of Sky & Telescopes' 2003 Hot Products of the Year.
Never slip adjustable height seat - The StarDust Chair cushioned seat has ridged steel hooks that cannot slip and drop you to the ground. The StarDust Chair seat moves only when you want it to move. Earlier observing chairs had seats that can drop abruptly if the seat is lifted slightly or the friction bar holding the seat gets dirty.
Foot Rest - The folding footrest means constant comfort at any height.
Spring Cushioned Seat - The same as a motorcycle or bicycle where long term comfort is critical. It tilts slightly so you always stay in full contact with the seat even if you lean forward or to the side. Allows longer and more comfortable viewing.
Dark Red Side Reflectors - They allow you to see the chair with a red night light. The reflectors are removable. No more tripping over a chair in the dark in low light conditions.
Chair sells new for $169. Mine is only a few months old, and it is in absolutely brand new condition. I am selling it only because I bought a new big dob and I am now using a ladder. $130. plus shipping.
