The backrest adjusting frame is very well made, it has very nice and thick rubber/foam handles to grab when adjusting and overall feels very premium compared to other adjustable benches with similar design I have used. It still works; its a little harder to invert it & open it up. They cost £20-ish, if you try to return you only get £3 back due to them coming from overseas. Adjustable shoulder straps. I would say the only drawback is that it is so big. Ordered my true size and they are perfect. I live in chronic pain, I have RA, bone spurs, fibro, flat feet, - I hurt all day every day. The Sennheiser Consumer Audio 504195 Headset - Wired has clear sound and the microphone clarity is very good. very happy The sound feels like listening to a 3d sound effect.
