Sofa over heat vent?

We placed a sofa over a heat vent in the living room. There's 3 vents in the room so this one is covered by the sofa. The sofa does have legs so it's about 2 inches off the floor, so the vent does have some room to circulate. Any concerns with this setup? Is 2 inches enough clearance?

Your sofa will be nice and warm, see if you can find something like this to direct the airflow to the front of the sofa

If you are worried about the sofa catching fire, there is no need for concern. The maximum temperature from the air vent is probably never more than 90F degrees.

Now for the purposes of heating efficiency (i.e. money savings) , Shabby has the right idea. The item in his image is $13.77 at home depot. However I think the sharp bend in this product will place a restriction on air flow.

If you have enough vertical space I would suggest one of these. Two for $7.85 at Home Depot.

Canada, Eh!!
We have used these and quite inexpensive.

Friends down south used as well but not for same reason. Their 2nd floor vents in ceiling so used deflector to keep air from blowing into their faces due to where bed is set.

Then in living room they have 3 [perhaps 4] floor vents. All covered with sofas and never noticed it being too hot or cold there. This particular room has no room on top, just roof.

Here's an interesting question: For houses with cathedral ceilings... since heat rises that particular room will be cooler so if do have a vent or two with sofa on top does that help in way to keep heat lower at least for a bit longer then without sofa?

Heat might melt any glue used in the sofa.

Good point... hopefully some staples there as well... guess it depends on quality of furniture bought.

In the example I stated above... been like that since mid 2000s. I'll ask them to check under sofa but more likely I'll have to check on our next visit.

How about avoiding all the hassle and just close the vent if you are worried. It will simply cause the airflow to go to the to other vents.

we use these in several of our rooms, not only for under the sofa, but just regular bedroom, I find it makes the room warmer, maybe because if not using any, heat loss is very fast next to cold exterior walls/windows

The increase to those two vents would be dwarfed by the reduction of flow from the one you covered. You'd be reducing the heat to that room by 33%, and you'd maybe gain 4% flow from the other two. All the rest of that flow would be (roughly) evenly divided amongst all of the other registers in the house.

Those plastic covers are a good solution, but be warned they're pretty brittle; the clear ones break REAL easy (maybe if you slide the couch into it, or step on it for some reason), but the white plastic ones have a little more give (but are ugly ... IMO). In your case, the couch is on top, so not a big deal, but just in case you're thinking of using them in other places (like my parents did for a while; I think I personally accidentally smashed 10 of those).
One who is offended by truth, has no place among those who seek wisdom.
