Strap for seated playing

I prefer to play in a classical position (otherwise I get wrist pain). Because of the body carve and weight of my Les Paul, this is difficult to so seated. Can anybody recommend a good strap that is the right length for seated playing in a classical posture? I'm 6'0'' tall.

Most are adjustable. It makes no difference, standing, sitting, lying on the floor ...... it's a guitar strap. Find one you like that is EASILY adjustable and , uh, .... adjust it to where you like. The ones with the sliding buckle, like the classic Ace stye 60's hippy strap, are easy to adjust and once you do, you can then measure the strap length and find one you may prefer that is that length, or has an adjustable range that matches, if you have a style or type preference.
