I have been looking for a new mattress recently. The reason I am looking for a new mattress is because I had this mattress for just about seven years I will say. I started having some back pain and figured it is time for a new comfy mattress. When I do online shopping, I am always looking for deals such as sales and promotional codes to help lower my total cost. Once I started to research mattress, I saw they were not cheap, and you cannot use any promo codes to help lower the price. By me researching mattress online I also, did not know how they felt so I will need to go in the store to test the mattress out. When researched mattress I wanted using the internet I used a secondary source. Once I went into the actual furniture store, I used a primary source. I choose this topic because this was the last thing I researched and at this time I will be getting a new comfy mattress that will help support my back.
