<prompt> Human: I am currently about to head into my senior year and finish my engineering degree. This final year will be paid for via scholarships except maybe 1000 for food for the year. Will have just over 10k in loans that I will begin to pay back next year.At the end of summer I will have about 9500 saved from working this summer. I am considering buying a new queen size mattress so that I do not have to sleep on a twin anymore. Is 500 for a decent mattress too much for someone in my position? I looked at some sub 300 that seemed decent, but so far prefer one that is about500.  <response>: A mattress is always a good investment, you spend a lot of time using it. 500 is reasonable for a decent mattress imo.
