What are the internal dimensions of the frame, where the mattress ? My current bed has too much clearance, so I can see 20cm of slats, which I am trying to avoid. A standard king size mattress is 150x200. This bed frame is 170 x225.
The internal dimensions / space where the mattress fits is designed to fit UK sized standard mattresses.
So a king size would accommodate a UK sized King mattress without any gaps or spacing
