For the price, there is nothing to criticize

The bed table is working fine, but could be a little easier, but still for the price 5 Stars.
Some concern I had, whether in bed really fit legs and duvet underneath, but that turned out to be unfounded. I use the table almost daily, for fatigue-free work with the laptop, -also in bed. :-)

I have done a few small modifications:
To put it again to say the laptop table also works without properly, these are just tips!

The weight of the laptop presses folded forward the table in the soft mattress. This is no longer just the mouse tray. Remedy I have created, in which I bought at the hardware store for 80 cents a meter silver foam pipe insulation for heating pipes, with a wall thickness of 1cm. Of this, I then cut two 3cm long pieces and pulled over the standpipe forward.
This is similar to the sinking forward again.
A pleasant side effect: when the legs are folded they no longer fall down when lifted, because some terminals mutually determined the foam rings.

The clacking "hinge" of Verstellmechanismuss I wrapped with electrical tape. So it no longer slackens rum.
