That's something I've never had to deal with. More than likely you will have to settle with one that locks in a 90 degree position. I don't think you will find one that is soft close too without having some motorized system. If the chest was taller they make an elevator which lifts a TV up to viewing position. It's expensive through.

Before you start thinking about putting two cylinders on each side, is there enough room to do that? I don't think it would be necessary though. If a single cylinder is rated at 56lbs then one on each side should do 112 lbs.

Mounting two of them on each side you would need to add some wood to the sides or have a metal bracket fabricated.

Looking at this data sheet it's not totally clear but it seems like item #8031UW, Gas Spring Kit are rated to 56lb for both combined, right?

You are correct. Usually the rating is for the single cylinder is how I got it wrong.
