Everyone’s body frame, weight and  spines are different, so selecting a mattress and pillow for each individual should be different as well.  Long term use of a mattress that’s too firm may cause improper support of the spine, to the point that muscles surrounding the spine can not relax.  Over time, this can injure the back, tendons and nerves.  On the other hand, long-term use of a mattress that’s too soft may cause body weight to be over-centralize, which concentrates pressure in one area of the spine.  This can also injure the spine and nerves.

Therefore, choosing a mattress and pillow that match your body frame, weight and the specific curve of your spine is the only way to prevent spinal injury or other health problems related to poor sleep.  However, you must do this with the help from medical specialist, using proven scientific theory and technology, take the MMT Test in order to get a custom-made  precise mattress and pillow that will give you the right support.

At the American Academy of The Spine, physicians successfully developed a method that can help individuals accurately find a suitable mattress and pillow after thousands of clinical tests.  First the person being measured is asked to lie on his back on top of the mattress or pillow.  When lying on a suitable mattress and pillow, the person being tested will experience complete muscle relaxation and show the greatest muscle strength.  Based on the muscle performance on the upper arms and thighs of the person being tested, we can accurately help him find the most suitable mattress and pillow. 

We can make adjustments in our mattresses so that they will be correct for an individual’s body frame and weight. That makes our mattresses so versatile that having one of our mattresses is equivalent to having 5 typical mattresses. According to our study, every time body weight changes by 8kg (+/- 2kg), over time. And this may require re-adjusting the mattress to get proper support. All 10Days retailers provide free and unlimited M.P.T test service to assist you in adjusting your mattress and pillow in order to meet your weight change (Note 1).  Even though a couples’ build and weight differ, we can still find the right support combination to give suitable support on both sides of a full size mattress so both of them can improve the quality of their sleep.
