It is virtually impossible to find a bed as comfortable as the one you sleep in comfortably, mostly soundly, the bed you call your own. Even if you sleep elsewhere, using a bed that has a good mattress, it just does not feel the same and sleep may not be as restful .
Then there are the features that aid sleep. Where I live, we are coming into the longer days. Soon mornings will be so bright by 4am that dark blinds will be needed. If we visit friends, invariably, they have flimsy white or light tie up blinds that fasten with many bows, or light coloured lined curtains that do not reach fully across the window, (though they reach down to the floor)which have huge clear light emitting gaps either side. Spend any length of time at such places and you will suffer very quickly from sleep deprivation.
You wake up, probably at some unearthly hour, bathed in sweat from the eye mask. It’s a good cover for slimming down facial features by excessive perspiration but as for encouraging proper restful sleep……
I have tried all sorts of things to deal with the light at small windows and average sized ones, some of them have helped. the really wide and long windows are a tall order with which to achieve anything.
