At Positech Innovation Inc, we understand that every wheelchair user has specific and unique back support needs. We offer a complete range of tension-adjustable canvas backrests to meet these needs. The Backus, Curvus and Curvus+ have been designed for different pathologies and users. But what's the difference between these three models, and how do you choose the one that's right for you? Here's a guide to help you make the right choice.  


Backus backrest

The Backus is a backrest designed primarily for users with flexible backs who need support. This model offers: 

  • Adjustable tension canvas: customize back support by adjusting the tension of the canvas. 

  • Removable straps: precise adjustments that adapt to the shape of the user's back.

  • Firm nylon structure: stable, comfortable back support. 

The Backus is therefore the ideal backrest for people whose posture requires support but without significant back deformity. It's perfect for natural posture while avoiding tension.  


Curvus backrest 

The Curvus is a softer, more flexible backrest than the Backus. It has been designed for people with moderate back deformities. This model offers:  

  • Stretch canvas with adjustable tension: hugs and distributes the curvus of the back, perfect for moderate deformities.  

  • Soft polyurethane foam: provides comfort and reduces pressure points on the back. 

  • Detachable, waterproof backrest: very practical for backrest maintenance. 

The Curvus is suitable for users with a slightly deformed back. This model corrects and supports the back while retaining flexibility for frolonged comfort.  


Curvus+ backrest 

The Curvus+ is designed for users with moderate to severe back deformities. It offers additional features for optimum support: 

  • Flexible, stetchable canvas: designed to follow the curves of the back, even when these are more pronounced, multiple strap adjustments possible.  

  • High-density foam 1'' thick: supports more severe deformities while offering superior comfort.

  • Elimination of molded backrest: the Curvus+ eliminates the need for footprints, because it's a very flezible backrest.

If your patient has more severe deformities, such as advanced kyphosis or scoliosis, Curvus+ is the ideal backrest. 


We also offer a range of products to meet specific needs and ensure adequate comfort and support. Remember that every user is unique and it's essential to choose a backrest model that best suits the user's needs and morphology. 

Positech Innovation Inc has the solution for you.
