Rubens, want a clever solution! I have the same bench, and I didnāt like it because the cushioning isnāt great and when I practiced for along time, it would get increasingly uncomfortable. Also, it squeaks. So a few years ago, I bought one of those āimported adjustable artist benchesā (i.e., not a Jansen but a Jansen lookalike), and itās been working great for me. I still have the Songmics and use sometimes when I need extra sets in for gatherings etc.
For those of you wondering, here are the prices, roughly:
Songmics: $100
Imported Artist bench: $470
Jansenās artist bench: $900
The imported benches about $100 more than when I bought mine.
