The MetaPal® M1-AP Attendant-Propelled Shower Commode Chair from SolutionBased is a highly adjustable mobility and hygiene solution designed for assisted bathing, toileting, and personal care. Built on the modular MetaPal M1 platform, it combines caregiver-friendly maneuverability with extensive positioning options for a more comfortable, individualized fit.
Equipped with four 5-inch locking casters, the M1-AP allows a caregiver to maneuver the user through compatible bathrooms and other indoor care spaces. Each caster can be secured to help stabilize the chair during stationary care, transfers, and positioning.
The adjustable seat height, seat slope, and fore-and-aft seat position allow the chair to be configured around the user’s body dimensions, transfer method, and bathroom environment. Adjustable armrests, footrests, and back support provide additional positioning flexibility, while optional cushions, headrests, and accessories make it possible to address a variety of comfort and support requirements.
Unlike a fixed-configuration shower chair, the MetaPal M1-AP features a modular design that can adapt as the user’s needs change. Components and accessories can be added or replaced over time, supporting long-term use without requiring an entirely new seating system.

✔ Over-the-toilet commode use
✔ Personal hygiene routines
✔ Home healthcare

Simple Adjustability
Pull-and-twist locking pins, referred to as Plunge Pullers, are positioned throughout the M1. They allow key components to be quickly adjusted and securely locked in place. This simple mechanism requires minimal effort, making setup and repositioning easy for both users and caregivers.
Height Adjustment | Seat Slope
The seat can be independently adjusted up or down without changing the frame height. Using our simple Plunge Puller system (no tools or clips required), seat height adjusts between 19″ and 23″. Height and slope are set in 1-inch increments, with up to 4 inches of front-to-back differential.
These adjustments support improved pelvic and trunk positioning and may enhance stability for users with limited trunk control, helping support better reach, balance, and overall comfort.


Seat Aperture
The seat aperture includes fore/aft (front-to-back) adjustment, allowing the seat to move independently of the frame and backrest. It can be positioned up to 2 inches forward or backward to better fit users of different sizes. This feature is standard on all seats.
Multiple Seat Styles
Seat options include molded or dual-layer Visco foam designs. Configurations are available with front, left-side, right-side, or rear openings, as well as closed-front styles. Custom sizes can also be made to order.

What is the chair’s weight capacity?
The supplied information does not specify a maximum user weight. Confirm the capacity of the exact chair configuration with SolutionBased or an authorized supplier before purchase.
Should the chair be professionally configured?
Yes. A qualified rehabilitation, seating, or healthcare professional should assess the user’s measurements, posture, transfer method, skin-protection needs, and care environment before selecting components.
What should be inspected before each use?
Check the caster locks, directional lock, seat, backrest, arm supports, foot supports, positioning accessories, pan, and all adjustment hardware. Do not use the chair if any component is loose, damaged, or functioning improperly.
Does this chair eliminate the need for caregiver supervision?
