Judy,
Got my chairs 3 years ago, took numerous tweaks to get it right for me. Had "elevated fully articulating footrests" Hated them! Took awhile and me being an insistent caller to get a fold up foot platform so I could be self-toileting again (with other foot rest felt like I was in stirrups on a gyno table and in-mobilized in chair). When foot rest down my feet are on it with soles parallel to floor. I've had- no problems. Have a sheepskin on seat of gel and air with self deflating'inflating valve (another tweak).

Hyper aware of areaS THAT MOISTURE MAY COLLECT (UNDER BREASTS, BEHIND KNESS, TOES, ETC) AND keep dry. Took awhile to get things absolutely right for me. Even small things affect my body, which DH finds unbelievable and amazing.
