Everyone wants wrinkle-free on almost everything: skin, clothes, and even bed sheets. Because of this, many splurge on dermatologist appointments and spend time ironing their outfits. Most homeowners prefer crease-free bedding sheets to enjoy a five-star hotel feel at home.

Since almost everything looks ideal when wrinkle-free, bed sheet manufacturers came up with crease-free sheets. Unfortunately, what may seem enticing to look at can be harmful to health. In this article, we’ll talk about the truth behind this type of bed sheet.

What Are Wrinkle-Free Bed Sheets?

Wrinkle-free sheets are designed to be resistant to wrinkling even after multiple washes. Some come in materials that are less likely to wrinkle than others, but most are treated with chemicals to ensure they won’t need ironing.

These sheets often have these labels:

  • Non-iron
  • No-iron
  • Durable press
  • Easy care
  • Permanent press



There’s no denying that the feeling of snuggling in pressed, crisp sheets is relaxing enough to lull you to sleep. Plus, crease-free sheets can make your space look more put together. By choosing wrinkle-resistant sheets, you can enjoy these benefits without the hassle of ironing, steaming, or spraying.

Besides less wrinkling, this type of bed sheet is made of different fibers. This means you can choose one that suits your sleeping needs and preferences. 

Here are other benefits that crease-free sheets offer:

  • Minimal or no ironing required
  • Fade-resistant
  • Mildew-resistant
  • Stain-resistant
  • Perspiration-proof
  • Moth-proof
  • Quick air-dry
  • Moisture-wicking
  • Durable
  • Budget-friendly



Your bed is supposed to make you feel as cozy, safe, and comfortable as possible. Unfortunately, if you’re using the softest wrinkle-free sheets to make your room extra presentable, you might be putting your health at risk. 

There’s a cost to achieving that crease-free magic. To make fibers stay in place and extra smooth, most wrinkle-free bedding sheets are treated or “finished” with resin.

This chemical process generally includes the use of toxic chemicals, including formaldehyde. The fabric is soaked or exposed to formaldehyde gases and then baked at around 149 degrees Celsius to prevent the fibers from wrinkling after multiple washes.


The Dangers Of Formaldehyde

Formaldehyde is a colorless gas with a strong, pungent odor. It is commonly found in different items in your home, such as household products, including pesticides, detergents, and paints. It may even be present in your clothes, pillowcases, and bed sheets.

Although it makes sheets look pressed and clean, this toxic chemical is mainly used as an embalming fluid. That said, it has potential negative health effects. In fact, it was classified by the International Agency for Research on Cancer (IARC) as a human carcinogen.

When breathed into the lungs or absorbed through the skin, one may experience chemical effects, depending on their sensitivity to the chemical and the intensity and length of the exposure. The Consumer Product Safety Commission reports that formaldehyde exposure may potentially cause these symptoms:

  • Eye irritation
  • Nose irritation
  • Throat irritation
  • Skin irritation
  • Coughing
  • Wheezing
  • Allergic reactions

Other effects due to short-term and long-term formaldehyde exposure include:

  • Asthma attacks
  • Chest tightness
  • Contact dermatitis
  • Difficulty in breathing
  • Endocrine disruption
  • Fatigue
  • Headache
  • Leukemia
  • Nasopharyngeal cancer
  • Nausea
  • Nervous system damage
  • Pulmonary edema
  • Rashes
  • Respiratory issues
  • Watery eyes


How To Look For Safe Wrinkle-Resistant Bedding Sheets

Wrinkles in your bed sheets may indicate that they’re safe for use. The drawback is they may make your space appear messy and uninviting. If you want beddings without a wrinkle in sight that don’t contain harmful chemicals, consider following these tips:

Buy Sateen Weave Sheets

Sateen refers to a weave pattern rather than a material. This weave uses a pattern of one yarn under three or four yarns over, giving it a heavier feel than other weaves. This allows sleepers to feel the sensation of weightiness, which is favored by many. It helps users feel warmer, making the ideal audience the people who sleep cool or live in cold climates.

The smoothness of the fabric and the amount of wrinkling depends on the tightness of the weave, which is determined by the thread count. Generally, sheets that are more densely woven resist wrinkles more easily. Simply put, the higher the bed sheet thread count, the less wrinkling there is. 

Look For Oeko-Tex® Label

The best way to avoid fabrics treated with formaldehyde is to shop smart when buying new sets of bed sheets. Besides avoiding purchasing sheets labeled “wrinkle-free,” look for the Oeko-Tex® certification in the product details.

Sheets that meet the Oeko-Tex® Standard 100 have been tested for the presence of harmful chemicals and are free of toxic substances. By choosing these sheets, you and your family will stay safe and attain peace of mind while enjoying your good night’s rest.

Choose Wrinkle-Resistant Fabrics

When it comes to buying sheets, you have many options. They come in different materials, including cotton, linen, silk, flannel, synthetic fabrics, and more. However, some fabrics are more prone to wrinkling than others. If you are looking for sheets that don’t wrinkle easily, try TENCEL™ bed sheets.
