That's a big score. Huge actually. Years ago, I worked in high-end furniture delivery. Ekornes are Norwegian made with fine leather. The chairs are designed to envelop and mold to your body.

Each of those is easily 1k+. Likely 1200-1500$ new each. They one in front doesn't look too worn or used at at all.

If you use real conditioner and keep the leather supple, those should last another 8-10yrs depending on use.

Finally, if you put both hands on each side of the headrest, recline all the way back, then gently but firmly tuck the headrest forward, you'll release the chair and headrest into full reclining mode, which is like lying down basically but your head stays facing forward and not staring at the ceiling. The guy in the pic could be even further reclined but still face the tv like that...

I still have my chair. I got it used free in similar condition but I used the crap out of mine and now it's in my man cave, no longer suitable for the living room. No joke, any company that's becomes familiar to your house will literally start calling dibs to sit in those. Enjoy...
