If you are thinking about buying a memory foam bed there are so many available that it may be difficult to determine which is best suited for you. Here are some tips about what you should be looking for. Be sure that the mattress will provide the proper body support with high density memory foam. The best way to determine this is to determine the density of the foam. Generally, the foam should have a density of between 5.3 lb. and 6.2 lb which will provide you with the proper support. Lighter grades of foam won't support your body and will not return to it's the shape that was in originally after a short amount of time. The memory foam should be sensitive to temperature. This is the one quality that makes this type of foam so unique. Your body weight will result in the mattress giving way when you first lie on it until your weight is evenly spread out over the entire surface of the mattress. However, once you have settled in, your body temperature will start to affect the material and cause it to soften in the places where the temperature has increased. The temperature sensitivity is what provides the comfort of a memory foam bed. Determine from the warranty if you are responsible for packaging or shipping. In addition, you need to know how long has the manufacturer been in business. Most lifetime warranties from a company that's only been in business for a short time are probably worthless. Inquire about a trial period. You need to try the bed for a while to determine if you have any problems. Should you decide to do this, cover the mattress in plastic to make sure that it stays sanitary so that the company can sell it again when and if you return it. Some people love a memory foam bed and some don't. You need to know that if you return the bed if there is a restocking fee and be sure that you will get a full refund. If you are only guaranteed an exchange only, you need to ensure that the store has many different selections for you to choose from. Compare the prices of retail stores to websites on the Internet. Many times, memory foam beds can be purchased on the Internet for much less than in retail stores and they have similar warranties.
