The pillows are great for someone looking for something cool and comfortable. We loved them so much that we bought a second pair. However, we were seriously disappointed with the odor of our last purchase. They give off a strong and indescribable chemical/burning plastic smell so nauseating that it’s difficult to sleep with. We’re hoping this issue will resolve with a couple more washes of the pillow cases, but am worried the source is the stuffing itself.

helped treat my sore neck

Color: White-cooling Basic, Size: Camping Pillow(Pack of 1)

This pillow — after dialing in the right amount of shredded foam — has greatly helped my sore neck. Initially, I had to remove some foam. Then I gradually added foam until it reached optimum comfort and support. It is also CPAP-friendly — especially when I position my head near the pillow's edge. (I am a left-side sleeper.) I like the travel size because I use a bulky hugging pillow to ease stress on my shoulder and elbow. That makes my side of the bed feel cramped if using a larger head pillow. A smaller pillow is easy to flip end-to-end in the middle of the night. I have spent lots of money on pillows over the years, but this is the best I've ever had for relieving [1] neck pain and [2] CPAP mask seal problems. Very comfortable, supportive, and affordable. I did not notice any unpleasant smell — and I am usually sensitive to that kind of thing. Would highly recommend.

Love them!

Color: White-cooling Basic, Size: Queen(Pack of 2)

Love them! After 10 years with our MyPillows, they finally lost their fluff. The reviews I read of the MyPillows of today were not good; they didn’t have as much filling as they used to. These pillows remind me of how fluffy our new MyPillows were 10 years ago!! You sink right into them and can mush them however and they stay. These are way cheaper than the Coop and it’s the same concept; add or remove the filling as needed. The cooling side is a huge plus too! You won’t be disappointed with these pillows!

A lot of comfort for a very inexpensive price

Style: 18", Color: Grey, Size: Twin

We needed a spare mattress, but didn’t want to have a dedicated spare bedroom but wanted a comfortable bed. Couldn’t afford these high priced mattresses these days like the air beds or luxury coil spring with gel which are thousands of dollars. Miss air mattresses, very comfortable and adorable and I like the flocked top on it. And it has the self inflatable pump which is very easy and inconvenient.This makes a very inexpensive alternative. Even if it only lasts 6 months or so you can buy a whole lot of these for a lot less money than thousands of dollars for the other beds. In tax is a wonderful brand. I’ve bought it many times. Their vinyl material is very thick and durable. Intex makes flotation devices, blowup rafts, beach floaties, Kayaks, etc. They have an excellent product & know what they’re doing.

Great Queen Size Air Mattress - NO Fuss

Style: 18", Color: Grey, Size: Queen

Great air mattress! Comfortable to sleep on. Powerful pump. Nice size. The bag to store it is very convenient and one of the easiest to put bed in once deflated. Reviews spot on with this product.
