So for the last 7 years, I have been sleeping on my wife's crappy platform bed that she bought at Gothic Cabinet for about $150.
A few years ago, while at the Architectural Digest Home Show (a great show for anyone interested in high end home furnishing), we saw an amazing bed from BDDW. It was made out of beautiful claro walnut which is a walnut that mostly grows in Northern California. It is a little more dramatic than regular, American black walnut. The bed is constructed completely out of solid wood and constructed out many different pieces of solid walnut, each piece of different lengths and widths, which creates a very dramatic, modern effect. It highlights the different colors of the woods and the different grain patters.
So three years later, my wife is still lusting after that bed. I decided to build one similar to that. I have made some adjustments- the headboard is much lower than the one we saw (forty inches high). The bed is pretty low to the ground. I used American Black Walnut and Curly Black Walnut (which has strong, dramatic grain patterns that are curly almost criss-crossing across the wood). I have a picture of the wood below.

The bed is almost done and looks amazing! All the bed pieces (headboard, footboard, and the rails) are flush with one another. It creates a modern look to the bed. For the slats that support the mattress, I used ash wood (that is very strong) that is 1 1/4" thick. That way, the bed will never sag. I am debating whether to do a little bit of inlay work on the headboard. I was thinking of maybe a couple of leaves in a light, contrasting wood such as maple or satinwood. I am going to finish the bed with a clear satin lacquer and then hand rub it down to give it a smooth satin feeling and low luster look. The clear lacquer will really bring out the grain of the walnut.
Also, the bed is completely collapsible, so its easy to move. The rails detach from the headboard and footboard, as to the slats.
I'll post some pictures tomorrow of what I have done so far.
