Fill & Construction
The Aricove uses a hybrid fill combining shredded memory foam with soft microfiber, giving it a unique balance of contouring support and plush comfort. The adjustable loft design means you can open the pillow and remove fill to customize the height and firmness , a feature found in only about 29% of pillows on the market.
At 5.25 lbs total weight for a king size, the fill density is substantial, and customers confirm the filling capacity is generous with easy removability.
Firmness & Support
Out of the box, this pillow ships at a firm firmness level with ergonomic cervical support designed for proper neck alignment. The hybrid fill provides the responsive contouring of memory foam while the microfiber prevents that stuck-in-the-pillow feeling common with solid foam.
Side and back sleepers get excellent support at default firmness, while stomach sleepers can remove fill to lower the loft for a flatter, more comfortable profile.
Cooling & Breathability
The Tencel Lyocell cover is naturally more breathable and moisture-wicking than standard polyester or cotton covers, which helps with surface-level temperature regulation. The shredded hybrid fill allows more airflow than a solid memory foam block.
However, there are no dedicated cooling features like gel infusion or ventilated compartments, so hot sleepers should weigh this against pillows with active cooling technology.
Care & Durability
The entire pillow is machine washable , not just the cover , which puts it ahead of most memory foam pillows that are spot-clean only. The removable Tencel Lyocell cover can also be washed separately for quick refreshes between full washes.
OEKO-TEX certification confirms the materials are free from harmful substances, and the hypoallergenic construction resists dust mites and allergens over time.

The Aricove arrives compressed and vacuum-sealed. After unboxing, give it a good fluff and allow 24-48 hours for the memory foam fill to fully expand to its intended loft and firmness.
Before your first sleep, remove or add fill to match your preferred height , side sleepers should keep more fill, stomach sleepers should remove some
Tumble dry on low after the initial fluff to help the hybrid fill reach its full volume faster
Warranty details should be verified directly with Aricove, as coverage terms can vary. The machine-washable design and durable hybrid fill construction suggest the pillow is built for long-term use.
FAQ
How do I adjust the loft on the Aricove pillow for my sleep position?
Unzip the removable Tencel cover to access the hybrid fill inside. Remove handfuls of the memory foam and microfiber blend until you reach your preferred height and firmness.
Side sleepers typically keep most of the fill for maximum support, while stomach sleepers may remove 30-40% for a lower profile that keeps the neck in alignment.
Can I wash the entire Aricove pillow in a washing machine?
Yes, the entire pillow is machine washable , not just the cover. At 5.25 lbs, you'll want to use a large-capacity washer.
Use a gentle cycle with mild detergent and tumble dry on low heat. The removable Tencel Lyocell cover can also be washed separately for quicker refreshes.
Is the Aricove pillow good for side sleepers with neck pain?
This is one of the strongest use cases for this pillow. The firm hybrid fill with ergonomic cervical support is specifically designed for proper neck alignment, and the adjustable loft lets you dial in the exact height needed to keep your spine straight while side sleeping.
The memory foam component contours to the shape of your head and neck for targeted pressure relief.
What is the Tencel Lyocell cover and why does it matter?
Tencel Lyocell is a plant-based fabric made from sustainably sourced wood pulp. It's naturally softer than cotton, more breathable than polyester, and wicks moisture away from your skin.
For a pillow cover, this means a cooler, smoother sleeping surface compared to standard pillow fabrics.
Is this pillow safe for people with allergies?
Yes. The Aricove pillow is both hypoallergenic and OEKO-TEX certified, meaning it's been tested and verified free from harmful substances.
The materials naturally resist dust mites and allergens, and the fully machine-washable design lets you deep-clean the entire pillow regularly to keep allergen buildup in check.
How firm is the Aricove pillow compared to a standard bed pillow?
It ships at a firm firmness level, noticeably denser and more supportive than a typical department store pillow. The 5.25 lb weight for a king size reflects the substantial hybrid fill inside.
If firm is too much, the adjustable design lets you remove fill until you hit your comfort zone , the microfiber softens the overall feel while the memory foam provides the structural support.
