Customer Reviews

  • “I purchased this mattress as a gift for my daughter’s 5th birthday. I’m sorry I waited so long to upgrade from her toddler bed. The mattress is comfortable and large enough for both of us to snuggle in during storytime. She sleeps soundly in it and is more likely to spend the entire night in her own bed. I like that it’s eco-conscious and doesn’t contain harmful chemicals. It’s not as firm as I expected — my only concern is that this will undermine its longevity, as there’s no way to flip the mattress due to the top gel layer. But overall, we are very pleased with the purchase.” – Elaine H
  • “We have used this bed ever since we brought our son home from the hospital as a floor bed. It is firm enough to be safe for infant sleep and very comfortable for momma when I feed him at night. We can change his diaper and feed him without ever having to pick him up. And if I happen to fall asleep nursing him, there is plenty of space. When I crawl out of bed it does not disrupt his sleeping.” – Kathryn
  • “My son has ADHD and has always had trouble falling asleep as well as staying asleep. He always complained about his mattresses (too soft, too hard, too lumpy, etc…) but he LOVES his BKB! The first night he slept on it he fell right to sleep and slept an hour longer than usual! When he woke up he said it was the most comfortable bed he had ever slept on. As a mom, that just thrilled me! He has had it about 6 months now and is still sleeping better and longer, he still loves his BKB!” – Cindy F
