Please reconsider the taupe. Everything will look very bland. If you choose your fabric carefully as to stain resistance and ease of cleaning, you can choose nearly any color you want.

I don't see a reason why the right taupe wouldn't work if you add color as you mentioned. Not a pro here but I tend to prefer my sofas in neutral shades.

Light grey walls and taupe sofas are both classic and harder to pull off really well than you might think. Some taupes pull green,some purple. Ditto the walls. So getting large samples of both matters. Especially matters when you get to the fun pillows,rug,accents stage ;-) I have a friend who purchased from Lazyboy who is very happy with her recliner sectional for her young family, too. It is pretty sleek,not a puffy marshmallow. She went with an ivory in a performance fabric. Braver than I was at that stage.

I would do a navy leather sofa. The navy works really well with light or dark grey and gives a bit of punch to the room. Keep the sofa simple looking and not poofy like a lot of the reclining types. For more color add a couple of purple and a mustard yellow throw pillows. Dont be afraid to add a bit of colour to your space, you will love the results

"Some taupes pull green, some purple."

I agree, hollybar. That's why a I mentioned using the right taupe. It can take some looking.

I'd do something like this. a heavy, textured sort of fabric w/dense, firm cushions. This will hide any errant drops of food or drinks, will spot clean and will stand up to children. color is great too. throw on diff pillows, get a patterned rug, a throw, some artwork.

bring in some camel color leather recliners, maybe a bold club chair, and you have a perfect backdrop.

Here's your taupe colored sofa. be careful w/chenille material. it won't last very long before looking beat.

I like that. (I saw that table lamp on Wayfair). love the media grouping, the velvet sofa and the warm leather and wood. Looks great.

I like the navy, too.
