Underblanket: The Natural Foundation for Optimal Sleeping Comfort
An underblanket is a thick blanket of approximately 2 to 3 cm, placed on top of the mattress, with a fitted sheet or molton fitted over it. An underblanket is thinner than a mattress topper and is primarily designed to enhance sleeping comfort and help regulate your body temperature optimally. It is also highly practical for neatly covering the gap between two mattresses.
Our underblanket made from pure new wool not only provides a wonderfully soft sleeping surface, but also offers pressure relief and excellent moisture regulation. Whether you are looking for extra warmth in winter, cooling comfort in summer, or relief from joint discomfort, at Weids Living and Sleeping you will find the perfect underblanket to elevate your sleeping comfort to the next level.

The perfect foundation for your bed: Comfortable underblankets
A good night’s sleep starts with the right foundation. While a mattress provides the support you need, it is often the underblanket that delivers the ultimate sense of luxury and comfort. An underblanket is an extra-thick layer, usually made from natural wool, which you place on top of your mattress and underneath your fitted sheet. The result? A noticeable improvement in lying comfort and optimal regulation of your body temperature throughout the night.
Why choose a wool underblanket?
When you choose a wool underblanket, you are choosing the unique qualities of nature. Wool is naturally self-cleaning thanks to the lanolin it contains, making it a very hygienic choice for the bedroom. Wool is also known for its excellent ability to regulate moisture and temperature.
Whether it’s winter or summer, wool keeps you comfortably warm without feeling clammy. What’s more, the dense structure of wool helps reduce pressure on the body, so you turn less and sleep more deeply.
How an underblanket improves your sleeping comfort
The biggest difference between a standard mattress and a bed with an underblanket is the immediate softness. While a “topper” is often used to adjust the firmness of a mattress, an underblanket focuses purely on the experience: warmth, moisture regulation and a soft touch. It creates a natural layer that improves bed ventilation and helps you wake up feeling refreshed every morning.
Care and securing your mattress underblanket
Using an underblanket is wonderfully practical. Most models feature sturdy elastic corner straps, allowing you to fit the underblanket neatly and securely around your mattress. This keeps the underlayer perfectly in place all night long.
When it comes to care, wool is surprisingly low-maintenance. Regular airing outdoors is often enough to keep the underblanket fresh. If a deeper clean is needed, we recommend professional dry cleaning or a dedicated wool wash programme to keep the natural fibres in top condition.

Frequently asked questions about an underblanket
What is the difference between an underblanket and a mattress topper?
A topper is a thin mattress layer (usually 5–10 cm) with a foam core. An underblanket is thinner, often made of wool or textile, and focuses more on climate control and the softness of the sleeping surface than on full-body support.
Do I sleep directly on the underblanket?
No. You place the underblanket on your mattress and then fit your regular fitted sheet over it. This keeps the underblanket clean while you still benefit from the wool’s warmth and comfort.
Why choose a wool underblanket?
Wool is self-cleaning, regulates moisture and temperature exceptionally well, and helps reduce pressure on the body.
How do I secure an underblanket to my mattress?
Usually with elastic corner straps, which allow you to fasten it easily and securely around the mattress.
Is a wool underblanket suitable for people with allergies?
Pure wool is naturally antibacterial and creates an unfavourable environment for dust mites, provided it is well ventilated. However, for people with a severe allergy to wool or dust, we recommend our washable synthetic underblankets.
Can a wool underblanket go in the washing machine?
Regular airing is often sufficient thanks to the natural lanolin. For a deep clean, professional dry cleaning or a dedicated wool wash programme is recommended.
