This lower position is beneficial for users who propel the wheelchair with their feet rather than their hands — a technique often used by individuals with hemiplegia or limited upper body strength. It is also useful for users with shorter leg length who cannot comfortably reach the floor from a standard seat height, and for those who perform lateral transfers to surfaces that are lower than a standard wheelchair seat.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhich wheelchair models is this kit compatible with?\u003c\/strong\u003e\u003cbr\u003eThe Super Hemi Kit is compatible with the Drive Medical Sentra Plus, Astaire Plus, Viper, and Viper Plus wheelchair models. If you are unsure whether your specific wheelchair model is compatible, check the model name on your wheelchair frame or contact us with your wheelchair's model number before ordering. Installing this kit on an incompatible wheelchair model may result in an improper fit or unsafe seating configuration.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoes installing this kit affect the wheelchair's stability?\u003c\/strong\u003e\u003cbr\u003eLowering the seat height changes the center of gravity of the wheelchair, which can affect stability — particularly rear stability. The Super Hemi Kit is engineered for use with the compatible models listed and is designed to maintain safe stability at the 15.5\" seat height when installed correctly. If you have concerns about stability after installation, consult with a physical therapist or seating specialist who can assess the configuration for your specific user.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eIs professional installation required?\u003c\/strong\u003e\u003cbr\u003eThe kit is designed to be installed on compatible wheelchair models and does not require specialized tools for most configurations. However, if you are not comfortable with wheelchair modifications or are unsure about the installation process, we recommend having the kit installed by a qualified rehabilitation equipment technician or contacting the manufacturer for installation guidance. Proper installation is important for safety and long-term performance.\u003c\/p\u003e","brand":"Complete Medical","offers":[{"title":"Default Title","offer_id":40388502552630,"sku":"10957HK","price":399.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1443\/4772\/products\/10957HK.jpg?v=1776406882","url":"https:\/\/www.precisionlabworks.com\/products\/super-hemi-kit-for-wheelchairs-lowers-seat-height-to-15-5-fits-sentra-viper","provider":"Precision Lab Works","version":"1.0","type":"link"}
