the Lewis Headboard (above) and the Riley Headboard (below) both from PB (I know...not the most original) but I am leaning towards them because they have a simple and classic shape that will never go out of style. They are also slipcovered and when you have children (and just finished a week where the little one had the stomach flu) the idea of washing the slipcover is attractive.
I go back and forth between the two because I don't know which shape appeals to me more - the rectangular or the camelback. I like them both.
Ballard's has the Stevenson frame which is sorta like the marriage of the two shapes above. They offer various fabric options including sunbrella. The height of the Stevenson is 54" (same as the Lewis above), however the Riley is 62" high! I taped both silhouettes out with painter's tape and I really like the height of the Riley eventhough we barely have 7 foot ceilings.
So, since we're on the topic, do you have a tried and true favorite when it comes to an upholstered headboard?
