Question 1

Do reviewers consistently say this mattress is lightweight and easy to handle for sheet changes and moving between rooms?

Accepted Answer

We have one customer review that specifically says this mattress is lightweight and easy to handle for sheet changes and moving between rooms; however, that point appears in only that review, so it’s not a consistent theme across multiple reviewers in our listing.

Question 2

What exact fiber is used in the 5" fiber core (for example: polyester, recycled polyester, cotton batting, or another material)?

Accepted Answer

The 5" fiber core is polyester fiber. Dream On Me lists polyester fiber cores for its firm “fiber” crib mattresses (some models are specified as 100% recycled polyester), while the Honeycomb product page itself lists only a “5" fiber core” rather than naming the exact fiber on that page.

Question 3

What are the mattress's external dimensions (length × width × thickness) and shipping/boxed weight — does it conform to standard US full-size crib dimensions (52 × 28 in)?

Accepted Answer

This mattress measures 52" L × 28" W × 5" H and the product (item) weight is listed as 8 lbs. [1] Yes — those dimensions match standard U.S. full‑size crib dimensions (52 × 28 in). The manufacturer listing provides the 8 lb item weight but does not specify a separate boxed/shipping weight, so we cannot confirm the boxed weight from the product page.

Question 4

Is the waterproof vinyl cover PVC-free and free of added phthalate plasticizers, or can you provide the specific material formulation/certification for the cover?

Accepted Answer

This mattress is listed with a waterproof vinyl cover and is Greenguard Gold and JPMA certified; Dream On Me states the mattress “meets/exceeds” phthalate and lead testing and Greenguard testing covers thousands of chemicals. [1][2] We do not have a PVC‑free/material‑formulation statement on file and therefore cannot confirm whether the vinyl contains PVC or which specific plasticizers (if any) were used; if you’d like, we can request the manufacturer’s material specification or third‑party phthalate test report and share it.

Question 5

Is the cover removable and machine washable, or is it permanently attached and only intended to be wiped clean?

Accepted Answer

This mattress has a permanently attached waterproof vinyl cover — it is not removable or machine washable. We recommend wiping the cover clean with mild soap and warm water as specified in the product description and care instructions.

Question 6

Does the mattress include reinforced/perimeter edge support to reduce sagging when a toddler sits on the side or when a fitted sheet tucks under the edge?

Accepted Answer

This mattress uses a firm 5" fiber core for consistent orthopedic support but does not include a reinforced perimeter/edge-support feature to prevent side sagging—perimeter reinforcement is not listed in the product features or user manual. The firm fiber core will resist normal compression, but if edge reinforcement is a priority look for mattresses that explicitly advertise “edge support” or foam‑encased/innerspring edges. [1][2]

Question 7

How is the 'vented construction' implemented—are there perforations, breathable channels, or mesh layers—and has airflow/temperature performance been tested?

Accepted Answer

We describe this mattress as having a “waterproof, vented” cover and say the construction is vented to promote airflow, but the product page and the included user manual do not specify whether that venting is achieved with perforations, internal airflow channels, or a mesh layer. Those sources also do not publish independent airflow or temperature-performance tests (the Greenguard/JPMA notes relate to emissions and safety testing, not airflow testing).

Question 8

To meet 16 CFR 1632/1633 flammability standards, what method or materials are used (for example, an internal fire-barrier layer versus chemical flame retardants)?

Accepted Answer

This mattress meets 16 CFR 1632/1633 by virtue of its firm 5” fiber core and waterproof vinyl cover rather than by a separate fiberglass “fire sock” or by advertised chemical flame‑retardant treatment. Our product page lists the model as a 5" fiber‑core mattress that meets/exceeds 16 CFR 1632/1633, and Dream On Me support has stated the construction uses fire‑resistant fiber (no fiberglass) for its crib/toddler mattresses. For context, foam mattresses often meet 1633 using a separate fire‑barrier layer, while fiber‑core designs typically achieve compliance through inherently fire‑resistant fiber construction.
