Description:
Everything you ever wanted to know about sleep but were too exhausted to ask.
We spend around a third of our lives sleeping. But what actually happens during those hours? This book takes you on a fascinating journey through the land of nod and out the other side.
• What are circadian rhythms and how do they affect our energy levels throughout the day?
• What are dreams for and how do they happen?
• What are the different stages of sleep?
• Do animals experience sleep the same way we do?
With clear texts and bright, distinctive illustrations, this is a great introduction to a subject that has fascinated us since ancient times, and an engaging tie-in to biology and natural sciences curriculums.

Fluffed to perfection.
Model: Soft-2PK, Size: Queen
I was a tad disappointed when I first opened the vacuum sealed packaging. They were flat and thin and disappointing. Once I fluffed them (took about 15 minutes per pillow) they were suddenly AMAZING. Fluffy and soft and perfectly supportive.

Ok
Model: Soft-2PK, Size: Queen
These pillows are ok. I would not purchase them again as they go flat, but they will fluff up again once you fluff them.
