For me, I would guess somewhere in the 500s is where I'd have to be sitting most of the time. 600s for not doing housework, even occasionally. So I'd say somewhere in there.

I had manboobs really bad when I was younger, enough to actually be tight in shirts along with my belly. But as I've gotten a bit older and having to lift heavy stuff, they've shrunk. Of course, my belly also grew a lot more, so maybe not...

Okay then.
Seeing as the initial post is now gone, have you ever broken a bed frame?
I for one managed to severely bend an old iron bed in college, and very nearly broke two steel tube ones in college.
These days I use a mattress on a foundation on the floor, but even that has a snapped board...

I'm fairly certain I've said this before, but if you're tall, 7 almost comes with 6. Cars, booths, and clothes don't fit if you're 6'3" and have a hard time bending over.
That being said, even with some weight lost, 7.

I had this problem too, but a couple rooms had bolted-in, cheap plastic seats. My fat ass probably irreparably bent three of those. I couldn't use the foldout desk at all.

Ok, this going to sound crazy, but put on more weight. I had some rashiness when I was about 300-330? And now I'm about 400 and haven't had rash for quite awhile.
I also wear boxer briefs tucked under the belly, which helps.

Damn, and here I thought I was getting some looks.

I would guess, just from your height, around 220, 230? Depends how the fat is distributed.

I'm there with pants. I need about a 58 waistband, and I hardly ever find anything at all.
Especially if I don't want to pay a lot.

Even those military style iron bedframes can sway a little under as much weight as some of us carry around, but it won't break.
I had a box under one in college that went in just fine at the start of the year, but got all scratched up on top by the end.
