The mattress topper and protector cheat sheet

What this sheet covers

This is the quick version of how to choose the layers you add to a bed you already own: a topper for comfort, a pad for cushioning, and a protector for spills. It sits next to our crib mattress sheet, which is about the mattress itself, and the sleep hub has the wider picture. The detail on off-gassing and the federal fire rule is in can mattresses be toxic.

The sheet sorts nine picks by how people shop for these products: a waterproof protector without vinyl, a five-sided version, a crib or toddler pad, a latex topper, a wool topper, and an organic cotton pad. There is no budget protector on it: we did not review one, and the tips say what to look for if you buy one. Latex and wool toppers and quilted pads are for beds, not cribs; a crib mattress should stay firm and flat with nothing soft on it.

The swaps in prose

The protector is the layer worth getting right, because it sits between the mattress and the sheet. Our pick is Naturepedic's waterproof organic protector pad, organic cotton jersey over a thin TPU layer, which the maker says is made without vinyl, PVC or phthalates. Sleep & Beyond's protector says the same of its layer and is TPU-coated on the top and all four sides. Avocado's uses a thin polyurethane film the maker says is derived from corn starch; its mattress-protector page does not use the words "vinyl" or "PVC", but polyurethane is not PVC. Avocado is also the one that reports a lab test with none detected (we did not open the reports), and the one that says plainly that its thin barrier can diminish with washing and that heavy or prolonged exposure may need a heavier enclosure; the same is true of any thin film. We rank Naturepedic first because two registers back it, one of them for this exact product, and it comes in every bed size. For a crib or toddler bed, Naturepedic's crib-size pad is the pick on our crib mattress sheet, and Avocado makes a crib-size version.

For comfort, the choice is between latex and wool. The latex topper we picked is from Sleep On Latex, sold as Pure Green: natural latex from organically grown rubber trees in Sri Lanka, with GOLS displayed and a certificate number on the page. Control Union's public search lists that company's GOLS certificate as certified (by company, not by model); the GOTS certificate we checked covers the optional organic cotton cover only. PlushBeds is the dearer latex option: its own site says the topper is not returnable (we did not check the Amazon listing's terms), and we could not confirm its GOLS in any register. Both are wrong for a household where anyone has a latex allergy. The wool topper is Sleep & Beyond's organic merino, the only wool topper we read, with GOTS confirmed for the company in the GOTS database; wool is not waterproof, so it wants a fitted sheet and a protector over it, and its maker says not to machine wash it.

The pad is a different job: it cushions and does not repel liquid. Coyuchi's quilted organic cotton pad is free of chemical finishes and flame retardants per the maker, with GOTS confirmed for the company. A mattress pad is a regulated product. In 2024 Avocado recalled about 55,000 of its quilted Organic Cotton Mattress Pad Protectors (model SFMPAVORG) for failing the federal mattress pad flammability regulation; CPSC reported no incidents or injuries, and the remedy was a free replacement (CPSC recall 24-330). That is a different product from the Avocado waterproof protectors on this sheet, and the notice does not mention them. We did not find a recall naming Coyuchi or any other maker on this sheet, and that does not tell you how any of them meet the rule, so ask.

How to read the label

A waterproof protector has a plastic film in it. Which plastic is the question:

• Vinyl (PVC) is the traditional cheap film. It generally needs plasticizers, historically phthalates, to stay flexible, which is the reason people avoid it near a bed; whether the amounts that reach you from a covered mattress matter is not established, so this is precaution, not alarm.
• Polyurethane and TPU (thermoplastic polyurethane) are different plastics, laminated as a thin film between layers of cotton. Naturepedic and Sleep & Beyond name TPU; Avocado names polyurethane. They are not PVC. Naturepedic and Sleep & Beyond also say outright that theirs are made without vinyl, PVC or phthalates. Makers of thin films say they wear out with washing and age.
• Polyethylene is a third film, used on some crib mattress covers (see our crib sheet). None of the protectors here use it.
• Wool's moisture handling is not a waterproof layer. It wicks vapor and holds some water; a spill soaks in.

Fluorinated finishes (PFAS) are a separate question. They are used on some fabrics to repel water and stains, and the CDC's ATSDR lists water-repellent clothing and stain-resistant fabrics among PFAS uses. We found no primary source that names a protector on this sheet as using them. Avocado reports an Intertek test with none detected in its protector, and says it publishes the reports; we did not open them. Sleep & Beyond states its protector is free of PFAS without showing a test. Naturepedic's page says traditional vinyl protectors can introduce phthalates and PFAS and that its design uses TPU instead, which is marketing about other products, not a finding. A maker's claim is a claim; a linked lab report is checkable, once you read which substances it tested.

Five certifications turn up, and each measures a different thing.

• GOTS is an organic textile standard: organic fiber and restricted processing chemicals. On a protector it describes the cotton, and per the makers the thin waterproof film is a permitted addition. Its public database lists companies, sometimes by product line.
• GOLS is the matching organic standard for latex. It covers the latex, not the cover or the other layers. Control Union issues it and lists certified companies in a public search.
• GREENGUARD Gold tests the finished product's emissions against limits set with children in mind.
• OEKO-TEX Standard 100 tests the textile for a list of harmful substances. It does not make a textile organic.
• MADE SAFE screens a product's ingredients against a list of substances known or suspected to be harmful.

If you came here from our old post on vinyl-free waterproof covers

Our 2009 post asked a parent's question, as a toddler moved to a twin bed: how do you protect an organic mattress without covering it in vinyl? That question holds, and this sheet is the current answer. The post recommended an AllerEase cover, which it described as made entirely of polypropylene and polyethylene. We have not carried that recommendation forward, because we have not read the maker's current page for AllerEase protectors, and the retailer listings we saw on 2026-10-23 describe polyester fabrics with a polyurethane or polyethylene layer rather than the materials the post described. If you bought one on our advice, nothing here says it is a problem; the label or the maker's page names the layer. The post also said vinyl "defeats the point" of an organic mattress; that is a preference, and this sheet says what is known about it. Where the post was right is that covers on the shelf often did not say what they were made of, and that is still the thing to check.
