While these sheets can be washed and dried quickly, they do have a tendency to shrink when you first wash them. Following this, colors have been known to fade quite quickly too.
Finally, while high-quality microfiber sheets are strong and durable, there are plenty of low-quality ones that are weak and rip easily. This poses a problem as you’re forced to pay for the more expensive items or else risk buying a sheet that rips.
All in all, there are many advantages and disadvantages of these sheets. They’re a great option for people with allergies, that’s probably their main selling point. In the end, it all comes down to your personal preference. If you don’t want a microfiber sheet, then there are other, more eco-friendly options out there such as good old cotton sheets.
