A circle has no head and no foot, which changes how a bedroom is arranged around it. Rectangular beds push against a wall because they have a back; a round bed can sit in the middle of a floor and still make sense from every side. That is why circular beds have always belonged to large rooms - they need space around them to read as circles at all.
Building the curve is the whole craft. A round base cannot be jointed from four straight rails, so the rail is built up in layers bent to a former and left to take the shape permanently. Get the former wrong and the circle is an ellipse that nobody can quite name but everybody notices.
The pierced headboard follows from the same thinking. A solid panel behind a round bed would look like a wall that had wandered into the room; cutting it through turns it into a screen, so light and the colour of the room behind pass into the design. Our master Indian artisans cut every opening by hand, following the grain so each thin section runs along the wood's strength.
