Tranquility Wave Mattress Cover

The cover is marketed for lowering cortisol and improving melatonin release via carbon fiber infusion, but its thickness is not stated anywhere, and there is no instruction limiting use to a single layer on the mattress supplied with the bassinet.

The product names the exact compatible model set directly, stating it only fits US Original mattress pads and is not compatible with Maxi, Maxi Tall or Pre-2020 models, with a model identification guide linked for buyers.

The mattress cover fits onto the bassinet's aftermarket mattress pad, but no federal standard or CPC is named for it anywhere, even though the brand publishes detailed fit and materials information for the same product line elsewhere.

The CPSC registry shows one recall for babybay: Babynest crib bumpers sold with the bedside sleeper, for a strangulation hazard, with no injuries reported. That recall covers a different accessory line than this mattress cover, so it caps at the top of this tier rather than pulling the score into negative territory.

The cover is certified OEKO-TEX STANDARD 100 Class 1 for the fiber blend, but the carbon fiber infusion's function and any waterproofing layer are not chemically disclosed, and no PVC/PFAS-free statement is made for this specific item.

The mattress cover itself carries an OEKO-TEX STANDARD 100 Class 1 claim (Confidence in Textiles) named directly on its own, which is the specific finished-item cert this criterion asks about, though no certificate number is published.

No emissions or off-gassing information is published for this mattress cover itself; the brand's VOC claims elsewhere apply to the mattress foam, not to this polyester-lyocell-carbon fiber cover.

This is a fabric mattress cover with a hidden zipper and no load-bearing hardware, casters or frame components, and no load rating or stability information is published for it.

The fabric composition (52% polyester, 47% lyocell, 1% carbon fiber) is disclosed, but country of manufacture, supplier and any warranty terms specific to this cover are not published anywhere we found.

The cover fits over the mattress with a hidden zipper and does not hang, clip to, or dangle above the sleep surface, and no cord, strap or small-parts information is published for it.

The fiber blend is disclosed at the component level: 52% polyester, 47% lyocell, 1% carbon fiber, with a removable zippered cover and washing instructions, all stated directly on this product's own listing.
