Ultra Slim Max Cool 2.75"

For stomach and back sleepers, we recommend starting with our 2.75" Ultra Slim model. It is our most popular and least-returned model. For many customers, the 2.75" height is the sweet spot that provides both ample support and proper alignment. For side sleepers, you may want to consider our 3.25" height to take advantage of the extra loft. All four heights have the same gel-infused memory foam with CarbonBlue™ phase-change coating.

Same heights, same shape. The difference is the foam: Max Cool uses the same gel-infused memory foam coated with CarbonBlue™ phase-change material that actively absorbs and releases heat (advanced cooling). Slim Series uses gel-infused memory foam with ventilation channels (good cooling at a lower price). If you tend to sleep hot, many customers find the Max Cool makes a noticeable difference. If you're unsure about height, the Versalayer is also worth a look. It lets you adjust height and firmness.

CertiPUR-US certified memory foam is tested for durability. It's designed to hold its shape and support over time. If your pillow is new, give it 24-48 hours to fully expand after unboxing. If it still hasn't fully expanded, see our pillow expansion guide for step-by-step help.

Our standard sized pillows are 25 inches long and 16 inches wide. They will fit in regular standard sized pillowcases. Due to their low loft, there might be some extra room in the pillowcase, but we very rarely hear complaints about the pillows fitting in normal pillowcases.

Like any new memory foam product, there may be a faint smell when first unboxed. It's harmless and typically fades within a few hours. Our foam is CertiPUR-US certified, meaning it's tested for low VOC emissions.

You can absolutely return the pillow in any condition within 30 days of purchase through Amazon for a full refund. If there's any uncertainty about height, the Versalayer is worth considering. You can try every height in one pillow.

It depends on your build and preference. Side sleepers generally need more loft than stomach or back sleepers to fill the gap between their shoulder and head. Our thinner models (1.75" to 2.75") are typically too low for most side sleepers. However, some side sleepers with narrower shoulders or who prefer a lower-loft feel do well with our 3.25" height. If you sleep in multiple positions, our Versalayer pillow may be the best fit. It adjusts from 0.75" all the way up to 6", so you can find the exact height that works for you.

A few common signs suggest your pillow may be too thick: you wake up with neck pain or stiffness, you find yourself pushing your pillow aside during the night, or you feel like your head is being tilted upward when lying on your stomach. Back sleepers may notice their chin is pushed toward their chest. If any of this sounds familiar, a thinner pillow designed to keep your spine in a more neutral alignment may help. Our pillows range from 1.75" to 3.25", so there's likely a height that better matches the way you sleep.

Many cooling pillows use a gel layer that conducts heat away from your head for the first hour or two, but eventually warms up and stops working. Our Max Cool series uses CarbonBlue phase-change material, which works differently. It actively absorbs and releases heat throughout the night to help regulate temperature over a longer period. Just as importantly, the CarbonBlue material is breathable and doesn't add a hard gel layer that changes the feel of the foam. The pillow still has the same soft, supportive memory foam feel; it just sleeps cooler.

Gel-infused pillows mix gel beads or a gel layer into the foam to draw heat away from your head. This can feel cool at first, but the gel typically warms up within an hour or two and can also make the pillow feel firmer or less responsive. Phase-change materials (like the CarbonBlue nylon/polyethylene cover on our Max Cool pillows) work differently: they absorb heat as they warm and release it as they cool, providing more sustained temperature regulation. Because CarbonBlue is woven into a breathable cover rather than layered as a hard gel slab, it doesn't change the softness or firmness of the memory foam underneath.

CertiPUR-US is an independent certification program that tests foam for harmful chemicals, heavy metals, and excessive VOC (volatile organic compound) emissions. All Bluewave Bedding pillows are CertiPUR-US certified, which means the memory foam has been tested and verified to meet standards for content, emissions, and durability. It's one of the ways we make sure you're sleeping on materials you can feel good about.

The memory foam itself should not be machine washed or submerged in water, as it can damage the foam's structure. If the foam needs cleaning, spot clean it with a damp cloth and mild detergent, then let it air dry completely. The removable pillow cover, however, is fully machine washable. Just unzip it, toss it in on a gentle cycle, and tumble dry on low heat. We recommend washing the cover every few weeks to keep things fresh.

With proper care, a quality memory foam pillow can last anywhere from 2 to 5 years. Over time, all pillows gradually lose some of their original support. A simple test: fold your pillow in half and let go. If it springs back to its original shape, it still has life left. If it stays folded or returns slowly, it may be time for a replacement. Our gel-infused memory foam is designed for durability, but like any pillow, it won't last forever. That's completely normal.

Yes, this is completely normal. Memory foam responds to temperature, so a brand-new pillow that's been compressed in packaging may feel firmer than expected for the first 24 to 48 hours as it adjusts to room temperature and fully expands. You can speed up the process by gently kneading the pillow, placing it in a warm room, or even running it through a low-heat dryer cycle for a few minutes. After a night or two of use, most customers find the foam softens to its intended feel.

Yes. Unlike pillows filled with shredded foam or down that can vary in loft depending on how they're fluffed, our pillows are made from a single piece of solid gel memory foam cut to a precise thickness. A 2.75" pillow is 2.75", not an approximation. This is one of the reasons we offer four specific heights rather than a vague "low" or "medium" loft. When the height matters to your comfort, you shouldn't have to guess.
