For many years, I always bought the same brand latex foam pillow. Unfortunately, it's not made anymore so I took a chance with something new. I'm glad I picked this one! Very comfortable and I like the medium firmness. Not too soft or too firm, perfect for me. There is a very slight odor but it is not overpowering at all and I know it will dissipate over time. I will be purchasing another one soon!

Excellent pillow. Soft but medium support. Fell asleep on it right away and it stays cool. Like sleeping on a cloud.

A Good Night’s 💤

Size: Standard (Mid Loft), Number of Items: 1

I’ve bought many pillows over the years and this pillow is by far the best for me. I am a back and side sleeper. Finally wake up without a headache or neck discomfort. I bought the medium standard. Just the right consistency. Not to soft not to firm. Stay cool pillow.

Confortable

Size: Standard (Mid Loft), Number of Items: 1

Excellent support. Always fluffy. It does have a smell but as recommended I let it air out for a day. I also washed the cover and had no issue.
