Hello. No issues heating room. His bed gets really warm because there is air going up in addition to left/right. I wanted no air to hit his bed and just deflect to one side. I’m not a hvac professional so my thinking may not be right. I just seems like a simple solution to just extend that piece of plastic on the ground and have it curved. I see this at Amazon but it doesn’t curve. Maybe I can just cut a hole on the side?Deflecto Furniture Deflector Air Vent Extender, Linking Clips and Tape Included, For Use with Floor Registers Up to 11" Wide, Clear (UFAD) https://www.amazon.com/dp/B0749KXCZF/ref=cm_sw_r_cp_api_glt_fabc_IXAdGb7M858P5?_encoding=UTF8&psc=1
