Could I put a wooden table and chairs on this? When I pulled the chairs out to sit on them, would they end up snagging on the seams between tiles?

You can put a table and chairs on top of our Eco-Soft + Tiles. If you do put furniture on these tiles, you will see indentations where the furniture has sat. To prevent this, we recommend placing furniture sliders under any heavy furniture. You won't typically be able to slide chairs in and out on these tiles. With furniture sliders, you would be able to. If you don't use them, we recommend picking the chairs up and moving them out before trying to sit in them.
