Does it have a solid, rounded disc bottom, or a ridged edge like enameled bottom pots that keep the center raised a bit?

It has a ridged edge on the bottom. It is raised anywhere from 1/8 to 1/2 in the center. I can not remember for sure.

All parts of it that make contact are flat. It has a slight upwards indentation in the outer most diameter of the ring, but the center circle goes down to the same level of the edges flatly. I guess the profile of the bottom is sorta like this: l\___/l. Hope that makes sense!

The bottom is flat, but, the one I ordered arrived with a chipped rim. It had to go back and I never reordered.

It does have a heavy bottom. The sides are neither thick nor thin, just standard sturdy for a cookpot.

The bottom is rounded, so on a flat cooktop things tend to slide to the center.

The smallest skillet is flat, but the other two have the raised grid around the bottom

On the bottom of the pan there is NO rim around the edge - BUT - there is a concentric circular pattern, which resembles the heating element on an electric stove. Althought it has a good bit larger diameter and has the "Lodge" logo in the center as well as their patten # on it. The cast mold of the circular pattern is about 1/8 inch thick. I assume this is to help prevent warping.

The inside bottom is slightly concave. The outside bottom is flat with a raised ring around the outside.

I am not currently looking at one, however there are no ridges so it is 'flat' in that regard. But, if my memory serves the bottom is very slightly convex so it is not 'flat' as in a perfect plane with the surface it would rest on. So, explained another way the bottom is very slightly domed up, but with no ridges.

I don't know what they mean by "raised center". As far as I can see, the bottom of this frying pan is perfectly flat. I think it will work just fine on a glass ceramic stove top.

Flat bottom. The rim you see in the photo is actually higher than the center.

The bottom outside surface is completely smooth. It appears to be ridged but when you run your hand across it, it is smooth. I've been very very happy with this pan.

The bottom is flat. The center is raised up a little higher than the outside, so it has about an inch around on all sides to catch the drippings in the corners. But no ridges.

Not sure exactly what you mean, but the bottom of the pot is flat. It does have rolled edges at the side though. Hope this answers your question.

No, Robert, it is somewhat rounded. The metal is also thinner making the two pots light weight, but once filled it is stable on the stove. It seems a little fragile, so treat it with care.

It has ridges that resemble the lid as pictured.... I've been using mine for years now and they still look as good as when I first received them!!!

I remember its bottom is flat (a little).I bought it as a gift to my Mom six months ago.I only checked it once.So, I can not remember it clearly.I am pretty sure my Mom likes it a a lot :)
