A waterproof, removable cover can turn a diaper leak into a load of laundry instead of a mattress scrub. These two dual-sided foam mattresses pair infant and toddler surfaces with zip-off washable covers, but one listing has conflicting dimensions that require extra care before buying.

Our Waterproof Washable Crib Mattress Picks
| Pick | Listed dimensions | Stage design | Cover |
|---|---|---|---|
| Hiccapop | Conflicting: 52 x 27 x 5.4 and 52 x 27.5 x 6 inches | Firm infant side; softer toddler side | Waterproof removable jacquard |
| Sleepah | 52 x 28 x 6 inches | Firm infant side; softer toddler side | Waterproof removable cotton |
“Washable mattress” means the cover can be removed and washed; neither foam core should be put in a washing machine. The washable cover versus waterproof mattress guide explains the difference.

CertiPUR-US listed
Hiccapop places firmer polyurethane foam on the infant side and softer memory foam on the toddler side. A zippered jacquard cover is listed as waterproof, stain resistant, removable, and machine washable.
Fit must be verified directly. The listing gives both 52 by 27 by 5.4 inches and 52 by 27.5 by 6 inches. Do not assume either set is current until the official listing and product label agree. Relevant owners also reported stuck or faulty cover zippers. One serious arrival-contamination report described bugs, so inspect the mattress and packaging before use and return any product with contamination or damage.
Why It Works
- Separate infant and toddler surfaces support a crib-to-bed transition.
- The zip-off cover contains routine spills and can be laundered.
- Rounded corners are intended for standard cribs.
- CertiPUR-US is listed for the foam component.
What To Keep In Mind
- Conflicting dimensions prevent an exact-fit assumption.
- A damaged zipper can make the cover hard to remove.
- Inspect for contamination, tears, dents, and incomplete expansion.
- It is not listed for mini cribs or playards.

Construction
Made in USA with imported cover
Sleepah states one consistent standard-crib size: 52 by 28 by 6 inches. Its firmer infant side flips to a softer toddler side. The cotton outer cover is removable, waterproof, and washable, while the inner cover is described as flame resistant without added fiberglass.
The listing ties CertiPUR-US to the foam and advertises additional certification language in the title. Confirm the current certificate and scope before treating any mark as applying to the whole mattress. Useful product feedback is limited, and one isolated comment said a product “broke” quickly without enough detail to identify the failed component. Inspect the core, seams, zipper, and cover before first use.
Why It Works
- The listed 52-by-28-inch dimensions are clear.
- A cotton zip-off cover simplifies cleanup.
- The infant and toddler surfaces are identified separately.
- The listing states the mattress is made in Arizona.
What To Keep In Mind
- Waterproofing is a cover claim, not a guarantee against every leak.
- Certification scope must be checked by component.
- The isolated breakage report lacks enough detail to dismiss or generalize.
- Keep the firmer side up until the crib and mattress instructions permit a switch.
How to Choose
Start with fit. Measure the crib's interior and compare it with current official mattress dimensions. Hiccapop requires special verification because its listing conflicts on width and thickness. Sleepah provides a clearer 52-by-28-by-6-inch specification, but every installed mattress still needs a snug perimeter and flat top. See what to avoid when choosing a crib mattress for the full inspection.
Then compare cleanup. A removable waterproof cover is easier to wash than a fixed wipe-clean surface, but the zipper becomes another wear point. Keep the foam dry, follow the cover label, and let every layer dry fully before reassembly. Our washable crib mattress cover guide and crib mattress cleaning guide cover the routine.
Finally, treat “breathable” as a construction claim, not a safety promise. Compare breathable and waterproof crib mattresses and read what breathable crib mattress means before weighing airflow language against waterproof cleanup.
Frequently Asked Questions
Can the whole mattress go in the washing machine?
No. Only the removable cover is listed as machine washable. Keep the foam core out of the washer.
Which mattress has the clearest dimensions?
Sleepah consistently lists 52 by 28 by 6 inches. Hiccapop's listed values conflict, so verify its current dimensions before buying.
Are both mattresses dual-sided?
Yes. Each has a firmer infant side and a softer toddler side.
When should I flip to the toddler side?
Follow the crib and mattress instructions for your child's stage. Do not switch based only on a comfort preference.
Does a washable cover mean it is waterproof forever?
No. Heat, wear, seam damage, and zipper problems can reduce protection over time.
What does CertiPUR-US cover here?
It applies to qualifying polyurethane foam, not automatically to every mattress component or every marketing claim.
Can either mattress be used in a playard?
No playard use is established here, and Hiccapop expressly excludes playards and mini cribs.
Compare the broader waterproof crib mattress picks and washable crib mattress picks before deciding which cleanup design fits your routine.
