This is the carpet

The marble blocks seem too clunky and space grabbing,and may be awkward to move when you are vacuuming.
The table with legs gives a lighter look,and lets you put extra books etc what have you,underneath.
Also,easier to stretch out your feet without a barrier.
YMMV,but do show us your solution.

I prefer the marble table.

Than you !!!

I'd look for a round glass top coffee table to break up the lines and show off your carpet.

the bentwood chairs don't look very comfortable.

I want to clarify the information that you've provided in order for everyone to provide the best assistance possible. Based upon two of the comments posted above, there seems to be some confusion.

1. The first photo in your post is of your current sofa - I assume that it has been included in order to try to clarify the color/type of fabric. You have described the color of your sofa as "beige" in a previous post + posted the below photo to show the color:

^^^The above looks different than the first photo in your post = it is difficult to know what the real color is. In your photo showing the whole room, it looks light gray. I assume that the true color is more like the first photo in this post.

2. You have posted photos of two coffee tables that you are considering for the room. I believe that the first one is a sliced teak coffee table - a comment posted above refers to it as a block marble table. Is it a wood table or stone? I think your current coffee table looks better than either of the two options that you've posted. The two rectangular solid wood tables look too heavy with your sofa.

3. The accent chairs that you want to add to the room are not comfortable chairs. Will these accent chairs be used for seating or will they be mostly for "show?" If they will be used, I would select different chairs. I don't think that you need to make the room look more "informal" by adding accent chairs that are woven like the ones you've posted.

4. Will the green accent chair in your photo still be used in the room?

Please provide more information!

This picture is when it was in the store.. , I am changing everything the green chair will be move .. I want to create an informal room because is so close to backyard.. thank you
