Environmentally friendly, waterproof, lightweight mattress grows with your baby

About this Product
  • Super light weight makes it easier to change the bed
  • WaveSupport core provides firm, comfortable support
  • 2-stage mattress grows with your child: firm side for babies, softer side for toddlers
  • Waterproof with a wipe-clean surface
  • NO PFCs, polyurethane, PVC, or fire retardants


Lullaby Earth has packed a lot of features into one crib mattress. As the name suggests, the Super Lightweight Crib Mattress isn’t heavy. Thanks to a patented WaveSupport core, it weighs in at just 7 pounds. Why does this matter? It helps when you’re making the bed. When you put the mattress pad and sheet on, you need to pull up the mattress, a task made more awkward by the crib’s intentionally snug fit and high sides. The trim weight of this mattress makes that job a little easier.

Next, it’s “two stage” mattress, which means that one side is firmer than the other. Young babies need extra firm support—in fact, it’s one of the most important safety features for your baby’s mattress. The Consumer Product Safety Commission recommends a firm, flat surface for babies. In the toddler years, you can flip the mattress over to the slightly softer “cushion firm” side to use it with a toddler bed. Both sides are comfortable for your little one. A reinforced edge means the mattress will still be going strong by the time your baby is a toddler, and it will stand up to bouncing. The reinforced edges combine with squared corners to create a snug and secure fit, helping to keep your baby’s arms and legs safe inside the crib.

Another feature of the Lullaby Earth mattress is that it’s waterproof and easy to clean, but made with safer, recyclable components like food-grade polyethylene and 100% PETE, food-safe materials. Waterproof mattresses easier to clean and help avoid the bacteria, mold, and mildew growth that can result from leaky diapers or nighttime accidents.

A major plus for Lullaby Earth mattresses is that they do very well on chemical safety. They meet all flammability regulations without the use of any flame retardant chemicals; they are free of questionable materials such as vinyl, PVC, phthalates, perfluorinated compounds (PFCs), and formaldehyde; and they are free of known allergens. It’s not an organic mattress, but if chemical safety and budget are running neck and neck on your list, the Lullaby Earth Eco-Plus Mattress with its lower price point is a good choice.

Bought this for our 1st daughter and used it while she was an infant and now as a toddler. Just repurchased it for our 2nd child. It has held up great and is so easy to keep clean- super lightweight as well.

It's light and so easy to change the sheets! My daughter sleeps well on it, so no complaints :)

I like that there's no concerns about toxic fumes but the price is somewhat steep. It fits our crib perfectly but there's a permanent crease in the mattress that formed quickly after use.

We are very disappointed in this product. This mattress is incredibly hard, not firm, hard. Our son absolutely hates it and is constantly waking. I ordered this mattress through Babylist because I received a gift card. Babylist did not carry the mattress our daughter has - the Moonlight Slumber Little Dreamer (which she loves) - so I assumed this mattress would be comparable because of its price point. Sadly, this is not the case.

Lightweight, infant and toddler sides to grow with your child.

It's the perfect mattress. Changing sheets is a breeze because it's so lightweight, it's waterproof, and it's 2 stage so I can continue to use it with my convertible crib/toddler bed. My daughter sleeps so well on it.
