I bought Vimle sofa-bed couple of months ago with the optional headrests. I'm pretty happy with the sofa itselft but headrests are kinda pain in the ass.

First of all the headrest are positioned / lean too much front. Maybe it's the bed mechanism beneath interfering for I don't remember having this issue when testing at the store. They are much more comfortable positioned when you have an extra pillow behind your back. Has anyone tried for example bending the headrest's metal frame to make them a bit more back leaning?

The second issue is with the height position. I'm not a tall guy, ~176cm, but the default (low) height postion is not comfortable for me. You can easily adjust that, but you have to do that everytime you sit down or after just lifting your head from the rest, because the headrest sinks down to the lowest position by itself. And I do this so very often (not really something I took in account when testing). The first issue with too-front-leaning-position also worsens the feel of headrest's low position.

Would any of you happen to have any neat and clean looking ideas how to prevent the headrest from lowering itselft automaticly? Cheers!
