FAQ:

Q: What is the best mattress for side sleepers?

A: The medium firm feel of the Bear mattress is ideal for side sleepers who weigh more than 130 pounds. While the comfort layers contour to the shape of the body, the mattress does not hug the body too closely or sink in too deeply. The responsive layers support the body while relieving pressure points.

Q: Are co-sleeper mattresses safe?

A: We’re all about safety, and that means you have to be sure the co-sleeper you select is safe. The American Academy of Pediatrics recommends that all babies sleep on firm surfaces. They have standards that all cribs, bassinets, and other safe sleeping surfaces must meet. Mattresses should be thin and firm.

Q: What is the best pillow topper for side sleepers?

A: Most side sleepers prefer pillows with medium to high loft because they provide the most head and neck support. Invest in a softer topper if your mattress feels too firm. Side sleepers can benefit from extra cushioning around the shoulders and hips if their mattress surface is too stiff or rigid.

Q: What is a bedside co-sleeper?

A: It acts as a bedside co-sleeper, giving baby their own space that is still close to mom with plenty of storage. One of the sides comes down to allow mom to reach her baby easily right next to the bed. You can raise the side if you want your baby to sleep alone.
