Great bed for my little one

My daughter has been loving her new bed. We are really impressed because it is extremely comfortable and she has been sleeping in later since she started sleeping in it. Money well spent!

Bed Snob says: Get this bed!

I used to own a luxury bed store, and for that reason, mattress shopping and receiving is usually less than fun. I am constantly comparing beds/mattresses to the very expensive and very amazing beds we sold....

Enter 5 Little Monkeys: I have a 3 year old who is transitioning to her big girl bed. Finding a mattress that is comfortable and isn't going to off gas, and isn't going to break the bank is a challenge. I was thinking we were going to get an Avocado mattress, but something said keep looking. I ordered and was really pleased with the price. It arrived quickly and we just set it up tonight for our daughter. She loves it! And she was BLOWN away by the monkey that came with it. The mattress protector and pillow are great too... I am a happy customer and will be referring everyone to 5 little monkeys!

One complaint

My only complaint is the mattress protectors don't come in King sizes - would buy in a heartbeat

If only...

Ordered the sleep system and an additional twin mattress protector. Love it all so much, wish the protectors came in King sizes for my own bed
