The Wayfair reps were excellent and went above and beyond to help me figure out the colour. It took the  manufacturer nearly 4 weeks to send a sample....
The bed is very good quality. The precuts to attach the wing were a bit messy but otherwise not a problem to put together with 2 people. The headboard is great. The colour is exactly what it sounds like...buckwheat. It is a tan/beige but the velvet gives it a distinct luxurious look. I can see that some folks got a bit of a green tint but it is very, very faint. Love my bed. Shipping was easy and no headaches coming across the border.
