I'm going to go out on a limb here and suggest that anyone born in the last 30 or 40 years probably don't know what bench seats are. Most cars, trucks, vans, and SUVs have had buckets for decades now it seems.
Back in the 50's and 60's, when cruising Woodward was king, most cars had bench seats. A bench seat is so called because it looks like a bench. Like a park bench. It goes all the way across - one big seat. It also meant that, whoever was driving dictated how close to the dashboard everyone in the front seat sat!
For sure, all of us driving Mom or Dad's Chevy Impala back then were victims to the bench seat. Now, the coolest part about the bench seat was that you let your girl friend in on the driver's side. With you. There was none of this running around the car stuff. You walked up to the car together and got in on the same side. One after the other, of course. AND, she only slid halfway across so you sat right next to each other. That way, you could put your arm around her, hugging and snuggling down the road. It was quite romantic. I am also reminded how we boys all had to put in extra hours behind the wheel in a parking lot somewhere, learning how to drive with our left hand - only. Things got more complicated if you had a stick shift, but that's a whole other story. Of course, there were those couple of times that the girl you were with sat next to the passenger door, but I think I only read about that happening. I'm sure that's right!
With bucket seats, sadly, those days are gone! Really a shame! Although I must admit I was happy about that when it was my daughters riding in the car with a boy!! Many of the early vans and minivans had bench seats in the back for awhile, but they were such a hassle to take out and put back in. The whole stow and go thing is a true God-send these days!
While there are a lot of webstores out there selling seat covers, there aren't so many selling covers for the bench seat. So if you are lucky enough to be driving an older model, and need some new bench seat covers, you'll have to do a little more work. But it will be worth it, for sure! Especially if you can talk your wife into going for another ride with you!
