Questions about Karup Design Ziggy

Does another slatted frame also fit into the bed frame?

Hello everyone, unfortunately we lost a few screws when we moved house. Is it possible to get replacement screws?

Why does the 1.80m version cost almost three times as much? At other online shops, the 3 sizes are slightly different, but at Galaxus, my trusted retailer, I'm supposed to pay sooo much more?

Is it possible to get this product also in carobbrown pine tree (Kiefer carobbraun)? I am very interested and would like to buy it in this color. Thank you!

how high can a mattress be when the slatted frame is screwed to the bottom so that it is level with the bed frame?

We would like to use a normal slatted frame and not the firm one that comes with the bed. Is there more experience about this? Do we have to put the slatted frame on the fixed one or can we exchange it?

We would like to use a normal slatted frame 2x90cm or 180. earlier questions on this subject were answered positively that this should be possible. does anyone have more experience in this? And if so, do you put the slatted frame instead of the fixed slatted frame or on top of it? We want the mattress to still sink into the frame.

Is it possible to install a metal slatted base instead of the slatted base supplied with the bed?

Are the slats that support the lying surface glued together or can they be moved downwards? I would like to buy a pocket spring mattress and thus move the lying surface downwards so that the mattress does not stick out too high.
