In cold temperature, at delivery, your mattress may take a bit longer to return to full sized from its compressed state.The expansion time of the mattress will vary as per the surrounding.Set Up: Simply take your mattress out of the box and enjoy watching it decompress. Jumping, walking, and sleeping on your mattress can speed up the process.
Green Tea Infused
The Zinus memory foam mattress is infused with green tea that helps eliminate odors. This is especially important in a kid’s room, where mattresses are subjected to extra wear and tear.

This mattress is comprised of four distinct layers that will support and provide comfort to your child throughout the night.
- Green Tea Memory Foam that keeps the mattress fresh

Safe and Gentle for your Child
Zinus’s mattresses are made with the highest quality memory foam. They are CertiPUR US Certified for durability, performance, and content. These mattresses are free from harmful materials, so you know your child will be safe throughout the night.
Available Options
I like that this mattress comes in a twin size and a narrow twin size. The narrow twin may fit better on your Kura bed, depending on how you choose to configure the bed. The mattress also comes in three colors: khaki, blue, and pink, so you can get a color that matches your child’s room.
Negatives of the Zinus Memory Foam Mattress
It is important to remember that this mattress is designed to be used on a child’s bed, like a Kura bed. The weight capacity is only 250lbs, so this will not be suitable for adults who need extra support from a mattress.
This mattress is compressed and sealed for delivery. It should be opened and allowed at least 72 hours to expand before use.
