Easy cleaning can mean two very different things: washing a cover or cleaning the core too. Newton lets you machine-wash its cover and rinse its core, while Lullaby Earth uses a removable waterproof 3D cover over a lightweight core. Fit and drying still matter as much as convenience.

Waterproofing
Toddler-side layer
Newton offers the more complete cleaning system. The removable cover goes in a washing machine, and the Wovenaire core can be rinsed in a shower or bath. This is useful after a leak reaches beyond the cover.
Cleaning the core creates a drying job. Water must drain out and the core must be fully dry before reassembly. The waterproof layer is described on the toddler side, so do not assume equal protection on both stage surfaces. Low-rating comments attached to the listing concern unrelated products and do not establish Newton durability; follow product instructions rather than those comments.
Why It Works
- Both the cover and core have stated cleaning methods.
- Standard 52-by-28-inch dimensions are clear.
- The stage-specific waterproof layer is identified.
- The mattress is listed as GREENGUARD Gold certified.
What To Keep In Mind
- A rinsed core needs complete drying time.
- Waterproofing is specifically tied to the toddler side.
- The core is rinsed, not machine washed.
- Breathability does not guarantee safer sleep or cooler temperatures.

Verify cover label
Lullaby Earth's cleanup advantage is a removable three-dimensional cover with a waterproof layer. Its wave-support core is lightweight, making it easier to lift the mattress for cover removal and sheet changes.
The product-specific fit and durability cautions outweigh simple convenience. Owners reported rounded-edge gaps, a raised or sloped middle, sideways movement, and progressive center sinking. One mattress arrived wet and contaminated with spiders. Do not use a delivered unit with moisture, contamination, gaps, a slope, or sagging, even if the cover itself is easy to clean.
Why It Works
- The removable waterproof cover handles routine messes.
- A lightweight core simplifies lifting.
- Infant and toddler sides are separately identified.
- Approximate standard crib dimensions are stated.
What To Keep In Mind
- Direct reports describe gaps, slope, and sinking.
- Arrival moisture or contamination requires return, not cleaning for use.
- The core is not listed for rinsing like Newton's.
- A breathable cover cannot make a poor fit acceptable.
How to Choose
Choose Newton if being able to rinse the core is the priority and you can allow enough drying time. Choose Lullaby Earth only when its lighter core and removable cover fit your routine—and the delivered mattress passes a strict fit and flatness inspection.
Build a laundry rotation before the first accident. Keep a fitted sheet and approved backup protection ready, then follow the washable crib mattress cover guide and crib mattress cleaning guide. Never remake the crib over damp layers.
Inspect the mattress whenever it is bare. Look for stains, trapped moisture, damaged seams, rounded gaps, dents, or slope. The crib mattress fit guide and when to replace a crib mattress explain when cleaning is no longer enough.
Compare washable crib mattresses and waterproof washable crib mattresses if you want other cover and core combinations.
Frequently Asked Questions
Can Newton's core be washed?
It can be rinsed in a shower or bath according to the listing. It should not go in a washing machine.
Can Lullaby Earth's core be rinsed?
The product instructions support removing its cover, not rinsing the core. Follow the current care label.
Are both mattresses waterproof on both sides?
Newton specifically places its added waterproof layer on the toddler side. Lullaby Earth describes a waterproof layer in its removable cover.
How long does a rinsed core take to dry?
Drying time depends on conditions. Do not reassemble the mattress until every part is fully dry.
What if a mattress arrives wet?
Do not use it. Document the condition and request a return or replacement.
Can cleaning fix a sag or sloped surface?
No. A mattress that does not remain flat needs inspection and likely replacement.
Does a removable cover eliminate the need for fit checks?
No. Reinstall the cover smoothly and check the mattress perimeter and surface every time.
