Here's the situation.  It's my husband's 40th birthday and he hates our couch, as do I.  It's not comfortable, and it's not at all easy to clean, so we have these ugly non matching covers that we use as you can see in the photo. 

I'm going to get him a new couch, but we now have a toddler and two dogs, so I want one that can be washed.  Performance fabrics are good, but there's no replacement for throwing it in the wash.  This significantly limits our options, but I like the Pottery Barn York slipcover sofa with chaise, which fits in about the same footprint.  

My husband generally likes the color of the blue sofa, he picked it out before he met me (and I'm fine with it!).  The coffee table is also something that he likes (and I'm good with also), so we're not ready to change that up now. The rug took a half century to decide on so that's staying, and the tile flooring must also stay.  

We'll probably replace the bar stools at some point.  The TV is a frame TV so we can change up the art above the fireplace (and yes, I know it's too high).  

  
This couch that I'm leaning towards this Pottery Barn York slipcovered deep sofa in the performance heathered tweed in Indigo, this one:

I've also considered it in slate in Performance Casual Chenille, this one:

[Here's my very basic mood board](https://preview.redd.it/m49lo6q58cah1.png?width=1286&format=png&auto=webp&s=031a765b9f213d15a48c68e4242eda651c7f696b)



My questions are:

* For this space, is this style of couch in a dark navy/slate too much dark color?  I'm used to the dark couch now and think it's fine, but I need outside perspective.
* If we go with the dark, is there a better option for accent pillows than the ones I have (tan / blue stripe) for this room?  Would leather pillows work?
* Would you put curtains or anything on the window (I like that it's open) and if so, what color to help balance?
* Any other colors that you think would be much better?

Is this dark couch going to work in this style?
