Amazon Basics Sturdy Heavy-Duty Non-Slip Platform Bed Frame, Steel Slats Support, Noise Free, Easy Assembly, No Box Spring Needed, 14 Inch Storage Height, Queen Size, Black

Honestly for a long time we just used simple metal bed frames from Amazon. They're really durable and were fully covered by our mattress so you couldn't really see them. As long as the bed was made nicely it always looked really well put together. We upgraded to a nice wooden one with a headboard and I honestly sometimes miss the simple metal frame because I'm constantly smashing my shins into the corner of the wood frame lol.
