This is a set of 4 legs for MUJI's leg-attached mattress (bed). There are some scratches, but the condition is relatively good. Please check the images for the condition of the felt pads on the bottom of the legs, as some are peeling off. I do not know the product number or compatibility, so please confirm this yourself before purchasing. Height: 10cm Diameter: 5.7cm Metal fitting length: 2.9cm, M8 *Please allow for some margin of error. I will refuse to sell to users with negative feedback.
