Hello! i have an L-shaped bench system in my entry way. due to the location and the way my contractor built the system, we have issues with top opening all the way, the too staying open on its own, and the lids slamming shut. the lid below the window cannot open a full 90 degrees because the window pane blocks it from opening all the way. this means we have to use our body to hold open the lid. i am looking for advice on hinges that can hold the top open (again not a full 90 degrees) and also provide a soft close. please see photos attached. thank you!!
