Want to add variety to your reformer workout? Extend your Align-Pilates M*-Series Reformer with the addition of a platform extender for an extra bit of padding for the feet when performing standing or kneeling exercises. The platform extender can also be used in conjunction with the mattress converter to convert your reformer into a complete flatbed. The fully flatbed can be used in conjunction with the Half Cadillac to add additional repertoire, or as a matwork area. Compatible with M*-Series reformers, except the M1. We also have Platform Extenders for A-Series, C-Series, and H & F-Series.
