Safety check — clear
We cross-checked this product and its manufacturer against CPSC recall notices, NHTSA child-seat recalls, FDA recalls and the AAP's safe-sleep criteria on August 31, 2026, and found no active recall or safe-sleep concern. That is a check of the public recall record, not a test of the product.
