I am getting ready to remodel my kitchen and wanted some opinions on flooring. Considering there are times that I am standing for long periods of time, I want something that isn't hard on the feet or back. My mom has ceramic tile and I absolutely hate it so I know it is out. So any suggestions would be appreciated.

DH is in floor covering. I don't know your budget but you may want to check out some not so common products. Rubber is one of the best for standing a long time. It comes in different textures and size tiles. Cork is also very good on the feet and legs.
Bamboo is popular and the better grades of laminate are attractive too.
I have ceramic tile, I don't like it much, but it was the final solution after many, many months of disagreement between DH and myself.

I would also suggest cork and hardwood floors (although wood isn't best for kitchens because of water). There are also those really nice laminate flooring that looks like wood--they are thick and super durable. They actually put some padding underneath which also provide a cushion for your feet.

If I were to remodel my kitchen, I'd either use hardwood or limestone.

I've had laminate (WilsonArt) for ten years, and I love it. It's easy to clean, is pretty durable (if you get a high quality one), and cushions better than tile. Ours still looks pretty darn good, after 10 years of abuse. Other than a few scratches from kitchen chairs and a small chip from where DH dropped a wall oven (!!), it looks good as new.

We're remodeling the kitchen next month and due to a change in layout, we have to replace the flooring. After investigating our options, we will again go with laminate.

i have dogs so durability is a must for my house.
my original floors were cork. it's comfortable and absorbs sound. the problem i had in the kitchen was that a leak caused seepage underneath the floor and the cork rotted. the odor was hellacious.
i had ceramic for a while and hated it as it was so difficult to clean and it was cold.
i now have something similar to porcelin but its more durable. it's very scratch resistant but is so hard that it hurts my feet to stand on it for long periods.
i also have laminate in my house and love it as its indestructible yet soft.
the hardwood is the prettiest but there are spots near the doors where water seeped in and its a little warped and discolored.

I have ceramic and I hate it. I would go with cork. You can also get Gel Mats. I know you can order them online, but I also saw them in Bed & Bath store.

My dh forced hardwood on me in my kitchen, and while the flow is nice and it looked pretty for like the first year, I hate it 10 years later. It is much more delicate than you would think. It's covered with scratches, has worn away in spots, and water does damage hardwood, so in front of your sink and fridge you will always have to be super careful. It is pretty, though.

I'd go with tile and a grout that is dark or is at least not super white.

I have a stone look laminate. Its about 8 years old, and still looks great. And is easier on your legs then ceramic tile

I watch alot of the decorating shows and cork is becoming alot more popular.

I have laminate over concrete and it is killer on my legs and feet. I imagine it would be better if there was something in between to soften it. My mom has a pier and beam foundation and hers is not as bad with the laminate.

My laminate is on a concrete slab, but they put padding underneath. I think that's pretty standard.
