Memory foam has been around for a while now, and for a long time, Tempurpedic was the sole manufacturer of its type. Over the years, many other companies decided to make their own version of the memory foam mattress, and this competition forced prices to come down, making memory foam mattresses much more affordable. However, if you are looking for a top quality product, you can still expect to pay a fairly high price. Other companies manufacturing memory foam mattresses include Sealy, Simmons, Dormia and Sleep Aids. Although Tempurpedic puts out an excellent product, and guarantees your satisfaction, you can't really go wrong, but they are not cheap. There are less expensive options for you to choose from, But be very careful and do your research before you invest in a mattress that won't live up to your expectations.
Not all memory foam mattresses are made the same, for instance, there are several different levels of memory foam density. Generally, the higher the density, the higher you can expect to pay. The products you will usually find range from 2.5lb density to 5lb density. The density is how much one cubic foot of the foam weighs, and the higher the density, the firmer the foam. You should avoid any foam having a density less than 3.5 if you would like a quality product. Be very careful of low advertised prices, as they may be either defective, bad pours of foam, low quality and run the risk of not being durable. 5lb density foam may be too firm for some, and just perfect for others, so the best way to get what you want is to try them out yourself, ask plenty of questions pertaining to foam quality and durability.
