If you intend to get a bed frame from ikea, take note that
ikea's bed sizes are proprietary. This means, standard bedlinen
won't fit ikea's products. So you can happily go robinsons and pick
out that 600 egyptian combed cotton bed set and it'll never fit any
of your ikea's bed products. Only ikea bedlinen can fit ikea's bed.
That's just a general reminder. Everywhere else, bed sizes are
standard, not ikea.
