J'aime bien la division dorsale de ce support de dossier. Le fait est que j'ai une légère scoliose et cette ergonomie permet d'adapter à ma déformation, le confort. Il y a cependant une date de péremption qui laisse peu de temps à l'utilisation légale du produit. Je le place dans mon véhicule et la longueur de la sangle d'attachement est trop courte: j'ai dû poser une rallonge pour entourer le dossier du véhicule.

should work as intended, although it takes some getting used to it at first. i was expecting it to be slightly larger; it sits way too low despite the "wings" being attached to their highest position. so i had to put a thin square cushion behind it for better support.

simple but works

very comfy

Nightmare to adjust the straps to tighten/loosen, but once you have it in place, it stays and it works great for comfort

An overall good backrest that's supportive but also flexible due to its split design. Each half of the backrest mounts independently to the backplate which allows for better flex. The plastic construction of the backrest is firm while still being comfortable. I wish the backrest had a vertical strap in addition to the horizontal one because it kept slipping down into the gap between my chair's back and seat whenever I got up. I was able to fashion a vertical strap using a bungee cord, but it would been better if it was designed with a vertical strap.
