I bought this house not too long ago and it has some sort of a finished basement. I brought some couches down there and a few rugs as well as my computer but it is still really cold.
There is insulation between the drywall and concrete wall, however, near the furnace there is only bare concrete, no insulation or drywall. I'm not sure how much that is affecting it all. The floors are tile. There are two bedrooms and one bathroom.
Regarding HVAC, there are AC/heating vents that push warm air into the basement, but it is clearly not helping enough. The upper level of the house is plenty warm, though. I've done a bit of research and I see there are no cold air return vents? I'm not entirely sure though.
I have created a video giving you a mini-tour of my basement:

Based on what I have described and what you have seen, what are your suggestions?
