I 'need' to reach the space above the exit door to collect the awkward noise generator on the table, but I can't just stack the assorted furnishings as the fan will blow any lightened objects to the right.
How do I reach the collectable?
The puzzle is the third part of 'Is it safe to ride?' just after the bit where you throw the safe and then jump on it.
I can't remember that puzzle exactly, so I don't know if it's possible in the context of this puzzle, but it seems like the most logical solution given you're in the bit of the game that teaches you this trick, so try the following:
In the Fluffy Dimension pick-up a piece of furniture (a table is ideal) and move to the position shown in the image.
Throw the piece of furniture so that it fly over to the location of the collectable.
Very quickly switch to the Slow Dimension.
Jump on the thrown piece of furniture.
Wait for the furniture to finish it's journey, delivering you to the collectable.
You might have to jump the last bit of the gap yourself.
If this gives you trouble because you can't get a high enough arc on the thrown object while still being able to jump on it, then you might be able to pull off the trick by instead throwing the object from as far back on the ground level as possible (with a higher arc) then running around to the top level and jumping on to it then (you'd need to swap to Slow very quickly after throwing) - without having the game here to test, though, I'm not sure which of the two presents the most reliable approach.
What you have to do is use a similar tactic as riding the safe but I would recommend using a table. First pick up your landing object in fluffy dimension standing a little ways back from the edge and hit the slow time dimension shortly after it crosses the end of the walk way there. Jump on your object while still in slow time dimension and you should be able to ride about half-way across the room before having to jump again and you should be able to make it.
I know getting this object took me several tries and lots of swearing trying to get the timing down right.
although that trick doesn't seem to work here.- why not? I don't have the game handy at work, so just curious, as it seems like the obvious action (especially if you're in the section of the game that just taught you that trick).
