My Dorm Room's Chair

We are all familiar with the typical dorm room setup...bland furniture, specifically designed to attract the minimal amount of lawsuits. You can imagine my surprise when I learned of a certain critical design flaw in my chair, so evil and malicious that I had to rename my chair to death chair
two components of this hateseat stand out:

the first, and less menacing, is the hinged back end. the idea was that since all the cool kids are into leaning back in their chairs and wearing leather jackets, chair makers could cash in on said leanage with an assisted leaning device. unfortunately, this only requires me to lean back farther than the permitted leaning amount, risking further harm than if the chair was normal

the second, and more dangerous component is difficult to spot because it is invisble. my chair holds a concealed weapon: an invisible laser. I mean razor. and really I mean sharp edge. but it still is invisible
here is a basic rundown of what happens each time the seat-beast takes another shot at my life:
1.I will begin to sit down, with enough time having passed since the last chair incident that I have at this point forgotten the cruelty
2.as I slide my right leg/knee down first, over the edge, the aforementioned invisible razor/fangs will tear at my knee, thirsting for blood, sometimes only ending up with cloth
the results are unpredictable and often gruesome. here is a small gallery of some of the death chair's victims:
not pictured: my lovable, and late, Green pants
After the small tear in my brown pants, I had had enough, and attempted to concoct a solution. the result, , was a static-y blanket that tended to get caught up in the chair so I removed it. so the death chair still hunts on today, but hopefully my genius solution will be posted later.
