I agree with everyting above, with the exception of the comment about staples. They are much maligned and misunderstood and several friends of mine who reupholster swear by them. In our marine climate stainless staples outlast even the best quality tacks and there is no rusting. The holes they create are smaller and the load is spread more evenly. A properly adjusted staple gun and the proper size staple can be set much more efficiently with no damage to the frame. I've had 5 pieces reupholstered over the years, the youngest in the 50-60 yr. old range (in original upholstery!). All were completely "ripped down", the frames checked for "racking" and the "wobbles" and tightened. All the webbing was removed and replaced, the springs reused and re-tied. Any horsehair (on the really old pieces) was cleaned and reused, fluffed up and secured with bridle ties. All the foam in the cushions of the newer pieces was replaced (I sampled the density of the foam before deciding which one to use), and wrapped in batting with a non-woven cover. Every piece came home looking wonderful and I've never regretted having them redone. Reupholstery is labor instensive. You are paying someone who lives locally to take the time to fuss over your furniture. They have worked hard to amass and perfect their skills, they have overhead, and they pay taxes, too. Personally? I would rather pay a tradesman/craftsman in my own country to breathe new life into something I find pleasing and works in my home. I agree than many of new particle board pieces are not worth the time required, but any good upholsterer will tell you that at the time the estimate is given.

Diana Bier - Here's a look now. Next dilemma is with our TV. This room, as much as I'd love it to be just a little den, is used as my space to watch TV when my kids are hanging in the family room. So my sister suggests getting a cabinet where the tv lifts up from inside... I'm considering that, but the room is so small I'm afraid it'll take up too much space and not sure I want to spend $3K for a french country one... would it be terrible to mount it on the wall above the 2 chairs and move those botanicals to another spot in my home?

I think your unique set is worth saving, but that light gray will not work with your setting. A neutral base fabric could even be a small texture, and then a range of toss pillows (use some black to pick up the black metal in your frame) & some caramel to tie in your leather sofa would update the appearance. Not sure where you're going to find fabric if your place is remote. BTW it looks like a great location. Maybe a dark neutral linen-like fabric for the big base cushion and toss pillows like these. Something a bit primitive to complement the location???? All these pilllow covers from Etsy. Maybe primitive fabric to complement your setting???? BTW it might be a good idea to change out your lamps. Add a floor lamp with black metal lets like this tripod floor lamp below.

Lots of variables need to be considered: How many cushions, both seat and back? Fixed cushions? Cording needed? Skirted? Style of sofa e.g. will it be tufted if no back cushions? A picture will help.
