My advice with Wayfair is do a reverse image search/search with Google lens. Here's the exact same bed on Amazon for about $80 less with an extra $20 off coupon. Plus you'll probably get it quicker from Amazon.

I can't speak to the quality of Mercury Row, but it seems like it's a name that's applied to "white box" furniture items. So probably low, but acceptable quality.
