One of those needs you don't know until you get it. this piece will still give you a single arm rest. how more flexible this piece feels knowing you can spread your legs or have a 45-90 degree body turn instead or routing head. guess this might be special in some rooms settlings. as it offers a napping bed. I covered mine with left over sized queen sheet. might look ugly with cover but It's such a nice piece I rather prolong it's life
