myMerino Mattress Topper Construction and Design Details
Sleep and Beyond took a very straightforward approach when designing the myMerino Mattress Topper. It is a patterned, 270 thread count organic cotton percale stuffed with 100% organic merino wool. This wool, which is derived from the sheep of the same name, is considered softer and finer than other wools. This not only creates a plush and comfortable sleeping surface but has been shown to help regulate body temperature as well.
The mattress topper itself is 1.5” thick and comes in eco-friendly, reusable cotton packaging. The pattern of the Topper is very simple and designed to equally distribute the supportive wool padding across the surface of the bed.
One of the things we really like about the myMerino Mattress Topper is that it is fully hypoallergenic. This is ideal for those who want to avoid skin irritations, rashes, and itchy eyes, which can result from sleeping on man-made materials. All aspects of the product are also certified free of pesticides, dyes, and carcinogenic chemicals.
Our myMerino Mattress Topper Review: PROs and CONs
The primary benefit of using a mattress topper is to provide additional support, comfort, and cushioning. Of course, not all mattress toppers are created equal. Below, we’ll list some of the most critical factors you need to consider before investing in Sleep and Beyond’s myMerino Mattress Topper.
PROS
You Don’t Have to Change Your Mattress
A good mattress can cost you anywhere from $500 to $6,000 dollars. That’s a pretty significant investment for any homeowner. However, with the myMerino Mattress topper, you can significantly boost your comfort without having to replace your mattress. At 1.5” thick, you can also use the same sheet sets, as it will not elevate your bed to the point where a fitted sheet won’t fit. Many users report that installing the myMerino Topper is like sleeping on a brand-new bed for just a few hundred dollars.
Helps with Temperature Regulation
One of the main reasons why Merino wool is so prized is its ability to regulate temperature. When placed in a cold environment, the fibers crimp and bend to trap air, providing insulation. When the climate is warmer, it helps pull heat away from your skin to keep you cool and dry. Such a feature is invaluable for anyone who has trouble sleeping due to poor temperature regulation or who gets overly hot or cold while they sleep.
All-Natural, Organic, and Hypoallergenic
All of the ingredients used in the construction of the myMerino Mattress Topper are all-natural, and that includes the cotton packaging. From the certified organic Merino Wool stuffing to the organic cotton percale, this Topper is ideal for anyone who has chemical sensitivities, allergies, or who has reacted to the chemical and toxins used in synthetic mattresses. Sleep and Beyond also reports that all of their products are sustainably sourced from cruelty-free farms and have been tested to be free of VOCs, carcinogens, and other harmful substances.
Better Sleep Without the Bulge
Many users report that the 1.5” thickness of the myMerino Mattress Topper is ideal, especially when compared to toppers that are 2” thick, 3” thick, or more. These heavier toppers can cause bulges on the top of beds as the stuffing inside moves and shifts. They may also necessitate that the user purchases a larger fitted sheet. Sleep and Beyond largely avoids this problem by investing in the quality of the padding rather than just increasing the amount.
Very Generous Factory Warranty
Sleep and Beyond offers a 5-year warranty on all myMerino Mattress Toppers. The warranty covers any and all manufacturing defects that may appear throughout the ownership of the product. Should the item be found to be defective at any point, they will replace or repair the item free of charge.
Works with All Sorts of Mattresses
One of the primary benefits of the myMerino Mattress Topper is that it can be used with almost any type of mattress. Users have reported seeing dramatic improvements in sleep quality whether they have an expensive Purple or Memory Foam mattress or an old model they inherited from the family. The Topper also comes in a variety of size options, from Twin and Full to Queen, King, and California King.
Effectively Blocks “Off-Gassing”
New and old mattresses are susceptible to what’s known as “off-gassing.” This is when volatile organic compounds from the manufacturing process escape into the air. As an all-natural product, the myMerino Mattress Topper does not off-gas when removed from the packaging. Moreover, it can block the emissions from the mattress to keep the air in the user’s bedroom free of chemical odors.

CONS
The Merino Wool Smell Can Take Getting Used To
Sleep and Beyond is careful to let buyers know that Merino Wool has a sweet smell that some people can find unpleasant. This is due to the all-natural production process, which removes the wool directly from the animal with no additional processing. It should also be noted that due to the high absorbency of the product, it can trap bacteria and should be cleaned in a way that limits exposure to moisture.
myMerino Mattress Topper: Size Options
The Sleep and Beyond myMerino Mattress Topper comes in five different sizes, each of which has a set amount of Merino wool filling. They are as follows:
- Twin 39x76in
Wool fill: 4.5 lbs. (30 oz. /sq. yd.) - Full 54x76in
Wool fill: 6 lbs. (30 oz. /sq. yd.) - Queen 60x80in

By offering a nice variety of standardized sizes, Sleep and Beyond allows the customer to simply choose the size that fits their mattress, ensuring a good fit every time.
Is There Anything Else You Need to Know?
Sleep and Beyond has outlined several distinct options users can use to care for their myMerino Mattress Topper.
- The first option is to use a washable cover. This will prevent the wool from absorbing as much bacteria or sweat and will keep it free of exposure to moisture.
- The second option is to sun and air the mattress cover regularly, as this will “revitalize” and disinfect the wool filling.
- The third option is to spot clean any stains or marks with a brush and mild detergent and then air dry.
- Finally, dry cleaning can be used in the event of bad stains or spills.
Sleep and Beyond donates 5% of every sale to charity. Though there is no way to tell which charity will receive funds from a particular purchase, the company has worked with CASA (Court Appointed Special Advocates for Children), GIFT (Global Initiative to Free Trafficking Victims), and Teen Cancer America
