Hi jramirez:
I’m sorry to hear about your bad experience with your new mattress.
If possible, I’d suggest that you return the mattress for a refund. In general, the brand you’re describing doesn’t use very high quality materials and your body impressions certainly aren’t going to get any better over time.
If you are able to get a refund, consider reading the Mattress Shopping Tutorial from this web site to assist you in starting the process over in how to buy a mattress. It’s a really helpful guide.
