Top Memory Foam Mattresses
Beds have come a long way since medieval times. When straw was packed on top of wooden slats and, luckily for us, today’s beds are far more comfortable too. One major revelation in the bed department over the past few decades has been the introduction of memory foam mattresses.
Memory foam was first developed by NASA as part of their space program. The memory foam was designed to help absorb the shock of re-entry into the atmosphere, which caused astronauts aches and pains.
Luckily, this technology has since been developed to make our nights much more comfortable and has been incorporated into mattresses, which mould to your individual body shape.
The unique cell structure of memory foam reacts to body heat and body weight. The hotter it gets, the more moldable the memory foam becomes.
Hospitals have recently started using memory foam mattresses for their beds. It helps in the treatment of patients with pressure sores, rheumatism, arthritis and joint problems.
How Memory Foam Mattresses React
Memory foam mattresses react to heat and mould around your joints for a comfortable night’s sleep; this means that your joints are supported and pressure points are reduced. Pressure points are one of the most common causes of joint and back pain, leaving you to toss and turn.
Memory foam is not just used in mattresses however; it is also used in mattress toppers, which can help make your current mattress much more comfortable. You can also buy memory foam pillows which help to support the head and neck, alleviating headaches, jaw ache, neck pain and tension and inflammatory arthritis.
The density of memory foam products can vary, and generally the higher the density, the higher the quality of the product. The depth generally ranges from around 2.5cm through to 5lbs per cft. Most research suggests that the optimum level of memory foam is 7 cm deep and 60 kg cm3. Memory foam mattress toppers tend to use lesser depths and densities than that.
