ECR4Kids 14" Three Rung Ladderback Chair - Asm (Pack Of 2)

Can these be painted without sanding first? I am assuming they currently have a finish on them, can it be painted over or is there no finish on them?

Will the 14in be too big for a two year old? I really don't want to buy one now and another set in a year or two

Do two or four chairs come with this order?

What is the weight limit for the 14" chairs?
