If you are buying an adjustable bed either because you want to be as comfortable as possible during your sleep or because you wake up in the morning with various pains and aches, the best thing you could do before picking an adjustable bed base is to buy a good memory foam mattress. Why? Because their cellular structure is able to bend to fit the contours of the frame and because it's able to withstand repeated compressions better than any other type of mattress. This means that, by feeling less pressure, the mattress will adapt to your body as well as stand the weight without being damaged. Check out the depth of the mattress Adjustable beds need bendy mattresses in order to function properly, which is why the depth of your mattress is vital: the thicker they are, the harder it will be to bend them. The recommended depth is of 12 inches, although many memory foam mattresses are not thicker than 8 inches which is good enough. However, if you are a side sleepers or if you are heavy, a mattress which is about 10 or 12 inches might be the best option for you to avoid having problems. Pick a mattress that isn't extremely heavy Even the best mattresses get weird shapes after they have been used for a while, which means that turning them around every now and then is a must in order to avoid this. That is why you should buy a mattress that isn't extremely heavy, so that turning it around every couple of months won't be a hard task. Pick an easy-to-clean mattress To keep your mattress in the best possible conditions you must make sure you can clean it without damaging it. Always ask the seller if it can be washed with water and cleaning products without ruining it. Have the possibility to return it if you are not satisfied Some stores allow you to try the mattress for a few days and return it if you are not satisfied, so make sure the shop you buy it from offers this option.
