Design Your Perfect Sleep
Redefining Sleep. One Perfect Alignment At A Time.
Realvellum started with a simple truth: one size does not fit all. Now, we’re building a new standard for rest with adaptive height technology, advanced partition knitting, and targeted ergonomic support. Clean, exceptionally breathable, and engineered to contour perfectly to your body. This isn’t just a pillow. It’s the future of sleep wellness.
Because your body isn't one-size-fits-all. We combine adjustable height with scientific ergonomic support to eliminate neck pain and keep you cool all night.
Standard pillows ignore your unique frame. We fixed that by creating an adjustable-loft design that custom-fits your specific sleeping position for instant neck relief.
We combined scientific contouring with hyper-breathable soybean fibers to create a pillow that actively aligns your spine while keeping you completely cool.

What Our Happy Sleepers Are Saying
Jessica L.
Standard pillows left me exhausted. The posture alignment on this is real I wake up feeling genuinely rested.
Elena R.
Finally, a pillow that isn't too thick for a stomach sleeper. I flattened it down to the lowest setting and it’s perfect.
David K.
Most ergonomic pillows trap heat, but this one stays breezy all night. Highly recommend the soybean fiber.
Sarah M.
Took two days to find my perfect height setting, and I haven't woken up sore since. Absolute game-changer.
Marcus T.
The contour perfectly cradles my neck whether I’m on my back or side. Premium quality.

From adaptive comforters to cloud-like pillows, every Mellow
product is designed to make sleep effortless.
Achieving your perfect sleep setup is effortless. The Realvellum pillow features an adjustable internal loft ranging from 5.1 cm to 10 cm. Simply unzip the cover to customize the fiber fill layer to your preferred thickness—whether you are a back, side, or stomach sleeper.
Yes. Unlike traditional flat pillows, Realvellum is engineered with an anti-traction slope and a central cradle zone. This design actively decommresses your cervical vertebrae and stabilizes your head, keeping your spine flawlessly aligned to prevent morning stiffness and tension.
Not at all. We replaced hot, dense memory foam with a hyper-breathable core blend of nine-hole fiber and natural soybean fiber. Combined with our open-air partition knitting, it allows continuous air circulation to keep you cool and sweat-free all night.
Both sizes feature the exact same ergonomic zones and adjustable height, but differ in surface area:
Standard (40 x 60 cm | 1.05 kg): Ideal for standard-sized beds and compact, streamlined comfort.
Grand (48 x 74 cm | 1.50 kg): Ideal for Queen/King beds and sleepers who prefer a wider, more substantial pillow surface.
Maintenance is simple. The outer partition-knit cover is fully removable and machine-washable just zip it off and wash on a cold, gentle cycle. To keep the inner supportive fiber core fresh, simply place it in a well-ventilated, shaded area periodically (do not wash the core).
