The frame is made of twelve pine strips, which are connected by upholstered tape. Particular attention is paid to the quality ( slats are dried in drying room ), so our slats are smooth, rounded on the sides so you do not damage the mattress. They are drilled, making it easier to attach the frame to the bed. As the manufacturer we will do any frame on request. Depending on your needs - you can order more stable frame - with more slats. Slats’ dimensions: 6x2cm Thanks for your trust.
