Stable IKEA double beds, manufacturer/beds/beds/overweight

Hello everyone,

we have a few problems with the stability of the double beds from Ikea. We are both not particularly light, together maybe 220 kg.

First of all, an Aneboda, which for a long time was only occupied by one person (me). From the end of 2008 no longer; and hardly had we lain on it together for one or two weeks, the rails on the sides ripped out. The sides were, after all, only about 10mm particleboard to the feel.
So definitely thicker and more stable wood: a Brimnes with drawers, that was probably 2009. On this one the side parts rest on the middle wooden foot but only by two to three millimeters; then the metal brackets bent and tore out, the particleboard bent off and then the middle lay lower. Until the next move I tried to keep it somehow patched up, then the bed went away.
So stay away from IKEA wood beds, next attempt: the metal bed SVELVIK in 2013. You constantly have to retighten the screws, which is simply annoying with this bed because they are hidden inside and you have to handle the special SVELVIK-own curved hex key through a small hole, as if you were a gynecologist. And now two of the screw heads are so stripped that you can no longer tighten them at all, and that’s almost that.

The only thing that has lasted all these years was the center beam.

I'm slowly fed up with IKEA beds. Is there some trick I have overlooked?

Which stable, reliable, durable bed, also for corpulent persons, can you recommend? Not only IKEA-specific, but generally.

Hello, I would first replace the botched screws and try whether they no longer come loose with spring washers, lock washers, or locking cement. Particle board is simply crap for a bed. Hemnes and TYSSEDAL are made of solid wood. Alternatively, I would look for wooden beds. They can certainly also build the beds accordingly for higher loads.
