Comfortable

I love my new serta cool relief pillow! Before I started this review I wanted to sleep on it a few nights. And I’m being completely honest, it’s comfortable. I’m a side sleeper and I run hot, I feel with my silk pillow case, this new pillow and my fan. I wake up fresh, and no pains around my neck.

Firm, Cool, and Holds Its Shape

I love, love this pillow! It is incredibly lightweight but still provides excellent support. It strikes the perfect balance of being firm without feeling too hard. As a side sleeper, it can be tough to find a pillow that works, but this one is absolutely perfect for me.It keeps its shape beautifully throughout the night and actually stays cool, which has made a huge difference in my sleep quality. Another major plus is the zippered cover—it’s so easy to take off and throw in the wash to keep everything fresh. I highly recommend it!

My Favorite Memory Foam Pillow!

I absolutely love this pillow!! I have gone through so many brands and different types of memory foam pillows. I hated all of them; except this one. Before I get into detail of why this pillow is absolutely perfect, I want to discuss memory foam. Memory foam is chemically made. Chemicals have smells, so yes, the pillow initially smells like the chemicals it was made from. The pillow comes completely wrapped in plastic which means the chemical smell is trapped inside the plastic as well. It's tightly wrapped to extend the life and quality of the product for when you receive it. Memory foam can and will eventually dry out. My husband is extremely sensitive to smells to the point we can't have candles in the house, use scented laundry detergent, or even perfume. He slept just fine next to the pillow the same night it was unwrapped and isn't able to smell it anymore. The smell quickly disappears within a couple hours of being opened. I love this pillow because it is firm, bulky, and incredibly soft at the same time. I have struggled with thick pillows because they slip out from underneath my head while I sleep. This one stays in place and my head sinks in. This is my favorite pillow now. The memory foam is incredible and very high quality. The pillow even comes with a warranty that covers permanent indentation on the pillow! I am in love with this pillow and highly recommend it.

Cool, soft, and supportive pillow!

I am pretty particular about my pillows - and this one has been awesome. I was hesitant to try it because other pillows have hurt my neck or my back. This one has just the right amount of support, while still being soft and comfy. The cooling cover is soooo nice, especially because I am a hot sleeper. And the memory foam is not too encapsulating - you can still move and breathe and it doesn't suck you in too bad. I have used this pillow every night for almost a month now and I wake up feeling great!

Comfort is just right

This pillow is perfect for back and side sleepers. It’s light weight yet good quality. We have been using it for months and it is still like new as far as how it feels and how it looks. I also love that it does not have a bad scent even when brand new.

King pillow

This king-sized pillow is incredibly comfortable and provides plenty of room to move around while sleeping. It has a soft, plush feel while still offering good support for your head and neck. The size is perfect for a king bed and gives the bed a more finished, luxurious look. It also fluffs up nicely and keeps cozy without being too firm

Very firm, but cools beautifully!

This Serta cooling pillow is a really nice pillow, and I was pleasantly surprised with how well the cooling features actually worked. This pillow is a king sized, and very generous in length. It features a patterned design on the outer cover, which zips up to protect the actual pillow inside. I do love how the cover is removable and allows the ability to wash as needed. The inside pillow is well protected, so I think as long as youbwash your outer pillow case and the protective zipped case for the pillow, you should get a LOT of use out of this! It seems very well made, stitches are tight and solid and does not give a cheap appearance at all. I gave 4 stars only because it's a VERY firm pillow. I need a softer cushion for my neck, and this one was very unforgiving. However, if you are in need of a firm, stiffer pillow, this one is for you! Overall, I would recommend this! Serta is a quality brand and they have been around for a long time. Personally, I will look for a softer pillow, but this one has great cooling features!

Keeps cool

I usually sleep with a cervical pillow because of neck pain, so this worked well for a couple of nights, but eventually, I needed to switch back. The cooling covered stayed cool throughout the night and the pillow is soft and comfortable. My husband has no neck issues and absolutely loves it.

Comfortable, but definitely has a smell

This Serta pillow lives up to its name and stays nice and cool. The memory foam isn’t too hard where you feel like you’re laying on a brick-it’s very soft and supportive. My main issue with it is the smell. There’s a certain sweet scent, almost like fake chocolate that is a bit overpowering. While you can remove the cover for easy cleaning (which is fantastic!), I believe the smell is the core of the pillow itself. I might try some odor remover and see how that does, because I’m very sensitive to smells. I haven’t had it long enough to say how it holds up over time, but it already feels sturdier than the other pillows I have in my home.

Nice and cool; slick and soft memory foam pillow

Very soft but firm memory foam pillow. It's a bit too thick (and uncomfortable) for me when sleeping on my stomach but on my back or side it's comfy. The zipper cover for the foam is an adequate case and cool to the touch. But it's very slick. I like to still use a matching pillow case over it, but it's too slippery to keep the case on.
