If you love minimal furniture with a bit of a nuanced look, checkout Lichen. It’s an archival collection that consists of designer furniture located in Brooklyn, NY. I discovered this store while I was living in Brooklyn. They have an amazing selection of home goods and other little trinkets. I most recently bought their bamboo divider and it is great for large spaces that need a unique way to be sectioned off.
Furnish Green in Chelsea has a huge inventory. Bedford Galleries is reasonable and has a bunch of midcentury.
Ry Modern is mad pricey but his stuff is so good, so I get it. Rubbish rarely posts, but nice stuff. Dobbin St is fine. haven't shopped there much.
Okay all are self explanatory except NY show place they’re like an auction house or some shit but at the end of every month they do a big tag sale with stuff that Didn’t Sell its a mixed bag but often there is furniture!! Best way to keep up is their Instagram Furnish green is my favorite tho curated and usually affordable and it’s nice that you can go in person
