The Marsden M-250 is an advanced powered chair weighing scale addressing one of the most persistent manual handling challenges in clinical weighing: the risk of back strain and patient injury when assisting mobility-impaired patients into and out of standard chair scales. A motorised seat lift operated by a handheld remote raises the seat to bring the patient to standing height, dramatically reducing the physical effort and two-person assistance typically required for chair scale use with patients who have limited lower limb strength or mobility.
Class III Approved under the NAWI Directive, the M-250 maintains the clinical accuracy required for diagnostic and treatment use while addressing the staff welfare and patient safety requirements of NHS Moving and Handling Policy.

Class III approval under the NAWI Directive confirms the M-250 is authorised for patient monitoring, diagnosis and treatment in NHS and regulated care settings. The powered stand assist mechanism directly addresses Manual Handling Operations Regulations 1992 obligations on NHS trusts and CQC-regulated providers to reduce manual handling risk to staff. By enabling single-carer operation for most patient-assist scenarios, the M-250 reduces the two-person call requirement that is a significant operational burden on wards and care homes managing patients with limited lower limb mobility. The 250kg capacity covers the clinical range required for general ward and care home use.
Does the motorised seat affect the scale's weighing accuracy?
No. The weighing mechanism and the seat raise motor are independent systems. The patient is weighed while seated, with the seat in its standard position, before the raise function is activated. Weight is captured and displayed with Hold engaged, ensuring the reading remains stable and accurate regardless of subsequent seat movement during the patient assist phase. The Class III approval confirms that the combined system meets the same accuracy standards as non-motorised chair scales.
In what clinical settings is the M-250 most commonly specified?
The M-250 is most commonly specified in rehabilitation wards and outpatient units working with post-surgical patients, elderly care wards with high proportions of mobility-impaired residents, and care homes where staff ratios make routine two-person weighing workflows unsustainable. It is also relevant to NHS trusts with active manual handling risk reduction programmes where the musculoskeletal injury rate associated with chair scale use has been identified as a specific risk in their risk register.
