Medline Guardian K4 / K4 Plus Wheelchair
Model: Medline Guardian K4 and K4 Plus Wheelchair
Availability: Ships from EnhDme — multiple seat widths, arm styles, footrest types, and tiers available
Lightweight, Durable, and Ready to Travel
A wheelchair that's genuinely easy to transport makes a real difference for anyone on the go. The Medline Guardian K4 and K4 Plus wheelchairs share a lightweight hammertone frame weighing just 33 lb., folding down for easy transport and storage without sacrificing the durability needed for daily use.
Breathable nylon upholstery and smooth-rolling, flat-resistant solid tires keep things comfortable and low-maintenance, while quick-release rear axles allow the wheels to be removed without tools. The whole chair arrives with tool-free assembly and is hemi-height adjustable for users who propel using their feet as well as their hands. The K4 Plus tier steps things up further, including a seat belt, anti-tippers, a seat depth extender, and brake extenders right out of the box, giving both users and caregivers added peace of mind without sourcing those accessories separately.

The K4 Plus tier is worth the step up for anyone who would otherwise need to purchase a seat belt, anti-tippers, brake extenders, and a seat depth extender separately — bundling those accessories into the chair itself is both more convenient and often more cost-effective than buying them individually later. Within the standard K4 line, the choice between desk-length swing-back arms and height-adjustable desk-length arms comes down to whether a customizable arm height matters for the user; the height-adjustable version offers more flexibility but at a different price point than the standard swing-back arm configuration.
