A lot's happening out there in the world of pillows
There is a lot more to a modern pillow than most of us realize, even after we've spent a good night on one. What was once a luxury item in the bedroom, or even a restricted item (for instance, used only by women in childbirth as was the case in Tudor England), is now a nighttime commodity with a lot of high tech design and engineering built in.
So today all of us can use a pillow (and we've moved past those Tudor restrictions!) and get both a good look on our made-up bed during the day, and a pleasant sleep at night.
The range of pillow designs will raise eyebrows, as most of us think everyone uses the plain old "pillow-and-pillow-slip" pillows our mothers gave us as children. But there is a very wide range of special use pillows and fabrics available to meet many of the niche needs we sleepers have.
Take pillow fabric, for example. You can buy luxury decorator pillows, or decorative accent pillows, that use beautiful or even quirky fabrics. They can be amazing beautiful things. My wife has some of these in a couple of our bedrooms and they really set off the bed. But it extends to all sorts of pillows, and you'll be delighted with the range of body pillow cases in the shops.
Or take size. There is a traditional size and shape for an adult's bed pillow in most countries. Here in the West, we all know roughly what that is. But in the Middle East, in Egypt, it's different. Those pillows are a totally different shape; they're long and narrow, stretching from one side of the double bed right across to the other. And they are not soft like ours, but hard and deliberately solid. Take your pick!
Then there are the many pillows and pillow cases which we find on chairs and couches. In fact, there are probably enough unique throw pillows to fill the largest warehouses in your city! I have noticed that in every country I've been in, in Asia, the Middle East, and across the West, houses often have small square pillows on couches. Only the decoration style is different.
Specialized pillows are a large part of the market. Have trouble with your back, for instance? Then there back support pillows, neck support pillows and lumbar knee pillows that all purport to be helpful for various back conditions. Snoring at night? You can find several types of sleep apnea pillow that seem to help some people with this disruptive problem.
