Go to the store and measure , this would make no sense to me

I keep a tape measure in my purse so I can easily measure anything I see while out and check out how it'll fit when I get home ... highly suggest getting in the habit. Sometimes stores will provide you with a measuring tape or accurate measurements, but you cannot count on it.

seems it will need quite a bit of visual and actual space, as it will need to stand from the wall a fair bit to avoid hitting it. you'll need to take a friend to the store with you to glide the bench while you hold a fixed object behind to see when it hits.

Thanks everyone, I thought someone might know the actual average swing space.

I did find out, most average 5-8 inches of space between the seat and the wall...not bad!
