If you want child friendly, this table has pretty sharp corners and I think it is too wide as well. Have you looked at the more "recycled wood" tables? Might be an interesting juxtaposition to the velvety sofa fabric.

Consider:

A couple of small cylindrical drum side tables - maybe of varying heights or colors that fit your scheme to draw interest. West Elm, Crate and Barrel, Wayfair or Target may have some great options!

Perhaps a large upholstered square, round, or rectangle table ottoman (in a kid friendly fabric , or even leather) - check out Houzz' shopping site!

Or, a large round tray table from Wayfair - form and function here.

Sounds good about how you plan to style once you've found your table(s).

Definitely add some colour to your space via area rug (be sure to research appropriate sizing for your space), then add some fluffly colourful pillows and artwork from colours found from your area rug. This will help marry the space a bit more for you!

Good Luck!

How about an upholstered ottoman with storage, red or orange? Add a big tray. Put your feet up? Not a gray rug again. Can you come up with something that appeals to you that is not gray. It doesn't have to relate to orange.
