Hi folks, I picked up this overall lovely Eames Aluminum Soft Pad Lounge Chair. One issue with this chair is it has a couple of indentations on the lower back cushion, probably from an object that had been placed on it over time. I was able to unzip the cushion and poke the dents back up, but then the dents became little lumps instead. It appears that the leather has been stretched a little and I'm wondering if there's a way to reduce the effect.
Also, there's no label on the chair. How old you think it is?
Thanks and Happy New Year to all of you!! 
David, would you mind sharing...
David, would you mind sharing why you guess it's 78? Is it the type of leather or the base? Except of those dents, the chair is in very good condition, especially with very little wear around the corners. With the dents, how long do you think it'll take for it to pop back up on its own? I wonder if rubbing it under some low heat from a hair dryer would smooth it out a bit, similar to what foxxy suggested with leaving the vinyl out in the sun.
Update
I've done some searches and decided to give the hair dryer a try. I started out with low heat and went a little higher meanwhile massaging the leather on the inside and outside of the cushion pocket. After about 15-20, it turned out fairly well. Immediately afterwards I put on some Leather CPR to condition the leather to prevent it from drying out. Overall, it's not perfect but I'm pretty satisfied and may try a second round of treatment later.
