No experience with tarva but I have the Stagstua bed, it’s incredibly sturdy and I have disassembled it 3 times to move and had no issues. It’s also pretty inexpensive. I also purchased the fyresdal daybed second hand and have had luck with it too. Just some other options if you decide against the Tarva.

I disagree with some of the blanket statement comments about quality. I’ve had a lot of ikea furniture for many years. If you buy the solid wood or metal, not the absolute cheapest options, and take care of it, it can last a long time.
