Search Engine Rankings dropped and altered

I’ve had some issues with my organic results recently and I’m not sure what’s going on

We are a furniture store, one of our top brands is Stickley. We used to rank 1st page on google for the search term “stickley furniture” Our home page is what was on the first page of google.

Now when you search “stickley furniture” we’re on the second page and google is displaying the Stickley furniture page of our website. We have not made any changes to the website in the last few months.

We have never done any Black hat SEO techniques or anything like that, all SEO has been done in house and has consisted of optimizing page titles, heading tags, image names and receiving links from relevant furniture websites by permission and never paid for any links or any of that junk.
