looking for mattress recommendations - need help!

hey everyone! im in the market for a new mattress and honestly have no idea where to start. i sleep on my side mostly, sometimes on my back, and i want something comfortable but supportive. budget is flexible but ideally not outrageous.

what mattresses have you tried and loved? any brands or types (memory foam, hybrid, spring, etc.) you would recommend?

thanks in advance for your suggestions!
