I purchased this headboard from Bow House Lifestyle, it's not currently on their website but I spotted in their Hungerford Shop new it would be a perfect fit!
Looking back through my notes on this project, the headboard costs £849.
If you would like to order one then I can put you in touch with Bow House Lifestyle and they can process the order for you. I have put their email below :)
