Mine are currently on my desk as well…but before that I used some metal stands from OnStage (I think?). There are other brands that make them as well. They’re pretty inexpensive a height adjustable. You could likely save some money in buying them used. After that you’ll likely want to decouple the monitors from the stands to keep your monitor response as true as possible. Lots of options here from IsoAcoustics to pucks, Auralex MoPads and Primacoustic RX series decouples…and likely bunches more. Many of those decoupler options can also be angled to help the directionality of your monitors should your stands not put them exactly in the sweet spot for your ears.
Hopefully that helps.
