There are numerous models of Flexsteel recliners and dimensions may vary. Check out their web site for models and dimensions HERE
We just sold our Flexsteel recliner and replaced with a Euro recliner. The Flexsteel was indeed what they call a "wall hugger" that doesn't need to move out from the wall, at not least to raise the foot rest. The chair was about 34" deep and required about a 2-3" clearance to partially recline the back with the foot rest raised. An additional 4" or so was required to fully recline the back. The front edge of the circular base, which sat back a little from the front edge of the chair, sat about 35" from the wall, but probably could have been a little closer. We usually turned the chair a little to the side to fully recline anyway.
I have also heard about many people who went to Lazy Boy for recliners. We couldn't find a Lazy Boy store near where we are. Also, from their web site Lazy Boy didn't seem to have many Euro recliners (which is what we wanted) so we went with a Euro recliner from Ekornes
. They are fairly expensive, but really much more comfortable than anything else we tried.
Another advantage to the Euro chair is that is is much lighter weight than the Flexsteel recliner we got rid of. I weighed the recliner and it was 112 lbs. I haven't weighed the Ekornes Euro chair yet (the opening in the circular base is too large to sit on our scale), but I know the chair and ottoman together can't weigh more than 50 lbs. The down side to a Euro chair is that I haven't seen any that was a wall hugger.
When selecting a chair, be careful that the base doesn't sit right on the edge of the slide. Our slide has a stiff plastic edge under the carpet that allows the slide to move easily over the carpet below. I wouldn't want to break down that plastic edge or the carpet on the slide might roll under when the slide comes in. Fortunately, we didn't want to locate our chair on the slide so we didn't have to worry about that.
Good luck in your search.
