ProFormer MR-300 manipulation table, made of gray synthetic leather, ideal for massage and treatments. - Model Name: MR-300 - Brand: ProFormer - Serial Number: 300007 - Color: Gray - Material: Synthetic Leather Thomson The lumbar area has springs that allow for up and down movement, and also allows for stretching of the erector spinae muscles. I think it will broaden the range of possibilities. I am selling it because I purchased a different bed. It has drop functions for the cervical spine and pelvis.
