Are both top and bottom ridged or is one flat?

both ridged; the lid puts pressure from the top so you end up with "grill marks" on both sides of the sandwich

Both ridged ! The only suggestion is to clean anything that melts and drips on it right away with a wet cloth or something because if you let it dry it's difficult to clean off the ridged area . But I love my pannini press :)

They are flat bottomed, but have a really tiny ridge running in the middle. I have not noticed any water deposits but I next time I run it through the dishwasher I can look for that specifically and I'll let you know.

One side has 1/4 inch ridges. The other side is flat with 2 circles about pancake size that take up most of the surface. Neither the ridges or the circles are very deep, about the depth of the spatula that comes with the grill.

It is flat. If you get them, make sure to not get the water level too high. I bought this for my grandson and his beta jumped out of the opening on the top and died.

Alan, my husband says that the bottom is completely flat. (I bought it for my husband's camping trips and I haven't got to use it yet!)

I am sorry I took so long to answer you. It is flat on the bottom. All the best!

There is a small ridge, but it doesn't hold it in place securely. I place the cup and Joe against the edge of the sink and this works as well as anything I have tried. I love this little guy!

I have this set and the bottoms do have ridges. I don't like this set mainly because the lid tops are metal and get very hot. (My old set had plastic ones)

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 plates are smooth. They are about 1" deep from base of plate to outside edge. Someone might have called that a "ridge" to indicate the plates are not perfectly flat.

It's NOT flat, there is a ridge. I have a brand new GE electric glass-top stove and it could NOT bring 3 gallons of water to a boil, even after an hour of heating on the "power-boil" setting, and trying to shift it around for maximum contact. This pot is useless on flat tops.

No there is not a ridge. The ribs run end to end and not on the edge. Hope this helps.

It doesn't have ridges. It's completely flat. And it doesn't have turn-off feature either. Plugging/unplugging is the only thing that turns it on/off.

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.

Yes, both top and bottom plates are ridged, and they are not reversible (IE the backside of the removable plates are not flat and not teflon-coated, so they're not intended as a cook surface.)

Bottom is flat with slightly round edge. I luv this pan, nice and big, easy to clean and if you follow the instructions for the first few used should last long time.

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