Queen Mattress under $150 (only need it for a year)

I’m a student on a tight budget and just need a queen mattress for about a year. I know cheap mattresses won’t be amazing, but I’m trying to avoid anything super thin or that sags immediately.
Without fiberglass.
I’ve been looking at Amazon/Walmart hybrids and memory foam beds, but it’s hard to tell what’s actually decent vs just marketing. I’m fine with “good enough for a year,” just want something that won’t be awful to sleep on.
Any recommendations for fiberglass-free options under ~$150? Or brands to avoid?
