If you wake up in the morning after a long, sleepless night, whether it be due to your partner's constant tossing and turning, or your nagging back pain, then you may want to look into buying a memory foam mattress.
By creating a depression and 'molding' to your body, memory foam essentially creates a separate sleeping area to your partner's much like sleeping in two different beds.
The 'molding' effect also helps to alleviate back and joint pain, as it takes the pressure off the shoulders, hips and knees, where pressure builds during a night spent sleeping on a normal mattress.
Memory foam was created by NASA originally as material for the seats in their spacecraft, but eventually it became commercialized and was picked up by a company named Tempur World and used to manufacture mattresses.
Eventually prices dropped and the mattresses began appearing in retail stores and the public discovered the magic of sleeping on memory foam.
Memory foam mattresses are sort of a halfway point between the comfort of a soft mattress and a support of a hard mattress.
They are normally a bit more expensive than your standard mattress, but they last a fair bit longer as well, so it is a sound investment.
Choosing the right mattress for you is quite a challenge as their are a lot of factors to consider including size, thickness, brand and of course price.
The memory foam should be at least 2 inches thick and at most 6 inches, as too little will do nothing and too much will be uncomfortable.
The rest really depends on the individual.
When testing a mattress, try to spend a significant amount of time with each one as it can take up to 15 minutes for the foam to react to body heat.
Test different brands and types of mattresses until you find the perfect fit.
Happy mattress hunting!
