As I said bumpy +-10dB each direction or +20dB depending on the reference point. That is quite the opposite from "good".I didn't get the same quality of bass at a show compared to home, but obviously the room was a different shape/size. I get good bass down to about 25hz/30hz in my bedroom, so quite a bit more extension than Harbeth P3ESR I'd imagine:

It looks relatively flat, but that is only be the case because the scale is to corse and zoomed out. It will look as many other rooms if you go for 5 dB steps and zoom in. If you have not, use 1/6 octave band smoothing then you can better see what is really going on.
I guess you will see too much reverberation time under 100Hz.
Again, I'm not offending you. I write this because you guessed that your bed will help in the low frequencies but it doesn't. BTW I'm dealing with similar problems too right now.
To show you the difference Harbeth C7ES3 XD in 14sqm:
That looks very good, doesn't it?
This is exactly the same measurement only with 5dB steps scale and 1/6 octave band smoothing instead of 1/1 octave band smoothing and 10dB steps scale.
BTW: The Harbeth P3ESR was an example and I used it because the tiny driver and cabinet can't overload a small room as much as a bigger speaker can. A P3ESR will also play deeper in a smaller room than the specs are telling because of room gain.

I didn't say that a bed won't have influence on the reverberation time, the question is where. I'm still very sure that a bed won't reduce deeper or mid bass, maybe upper bass. The other thing is that it can do worse if it has influence at a frequency range where is a drop already.I expect a bed will make quite a noticeable improvement in reducing RT60. My ex-music room sounded much better after a king-size bed with plush fabric/foam headboard was introduced, far better than it ever did when I used the room for listening to music, all I had then was a 2-seater sofa and thin rug, all the other furniture was made from wood and highly reflective, including the sofa which was leather!
It's very difficult to produce accurate measurements of a room, and I would personally take any you see with a pinch of salt (including mine). As the sound is bouncing around all over the place in all different directions, it's adding and subtracting (in and out of phase). So as you move the microphone around, you'll get different measured results.
The moving microphone technique is supposed to be one of the most accurate ways to measure, because you're not just measuring in one spot. I haven't bothered because playing test tones shows an even frequency response in my room. I've been able to find bass problems in a friends room by just listening to test tones. It's really not too difficult.
I don't know why your in room measurement doesn't show a sloping down frequency response (the top one). A flat anechoic measuring speaker (as mine is) should have a downward slope in room. Yours looks flat from 60hz to 2khz which doesn't look right to me. It does look like there's a ton of smoothing or something, but even so, it shouldn't look like that unless the speaker isn't flat to begin with.
I don't believe for one minute my bed does nothing, it's more of a question of how much and at what frequencies.
