Alvar Aalto stools  

Looks
Looks very nice to me. I've never restored anything like these, but I would think perhaps a light hand sanding and staining could have them looking great.

.
Postwar Aalto pieces (which these are) have a quite thick clear cellulose finish, so 'light sanding' will just scuff the finish and 'staining' will result in the stain falling off because the impermeable finish is still there....You can either strip and refinish or burnish the finish thats already there to clean it and give it a bit of a shine.

Hi
Any markings on the bottom?

patina
I would leave as I agree they do have a nice patina just wasn't sure if they where to bad to sell on if I decided to , no markings to bottom

Hi
I would leave them as is. They will certainly fetch more than $10 each (?) if you decide to re-sell them.

Yeah
It's a stool, a utilitarian object that is also beautiful. It's okay to show evidence of utility. Do you "restore" your hammers?

What?. Sand and stain?
Are you crazy Lucy?
Patina, patina.
If you want fresh and new, buy new and shelf it and don't use it.
Clean it. Fine if soiled and dirty.
