如何在可调节的床上处于零重力位置？
when you’re in the “zero gravity” position, your legs and feet are elevated at a higher angle than your head. this creates a feeling of weightlessness that can alleviate lower back pain. the zero gravity position can also benefit people with low blood pressure and other circulatory issues.
zero gravity is a standard feature on today’s adjustable beds, many of which allow you to elevate the head and feet at a wide range of different angles. however, some do not include this option. if zero gravity is important to you, make sure the adjustable bed you’d like to buy allows this type of positioning.
if you don’t properly anchor your bedding before elevating your adjustable bed, then your flat sheet – and possibly even your fitted sheet – may fall out of place.
each fitted sheet has a “pocket depth,” which refers to the tallest possible mattress the sheet can be used with. if the profile of your mattress exceeds the sheet’s pocket depth, then the elasticated corners can easily slip off. make sure the sheet and mattress are compatible.
you may be able to anchor the flat sheet by simply tucking its edges beneath the mattress. if this doesn’t work, consider a flat sheet with corner straps that grip the fitted sheet and provide extra stability. you can also invest in a “sheet suspender,” which is essentially a large rubber band that runs around the side of your mattress and keeps the flat sheet in place.
