Weight limits vary by model. Common limits shown are about 20 lb and 25 lb (one listing gives a limit of roughly 9 kg). Check the specific product listing for the exact limit for that model.

Age ranges depend on the model and mode. Listings commonly show ranges such as 0–3 months, 0–5 months, about 0–6 months, and up to 0–9 months. Always confirm the recommended age for the specific product you’re considering.

Frames are typically metal or plastic. Surface and trim materials vary; fabric coverings and fills are often polyester, linen, or cotton blends. Many models use breathable mesh side panels for airflow and visibility.

Dimensions vary by model. Typical height ranges are about 28.3–32 in, widths about 20.5–25 in, and depths about 34–39.5 in. Overall weights reported in listings span roughly 21.85–30 lb. Check the product page for exact measurements for a given model.

Most listings indicate adult assembly is required. Commonly included items are the bassinet/frame and sometimes a mattress or pad. Other listings may include accessories such as a foam mattress, mosquito net, storage basket, travel bag, and attachment straps—availability varies by model.

Certification varies by listing. Some state compliance with ASTM standards; one listing references meeting AAP and NIH guidance and federal testing. Several listings do not list a certification. Verify the safety certifications for the specific product you’re viewing.

Listings commonly describe attachment straps, anchor plates, or resistant plates designed to hold the bassinet flush to the adult mattress. Some models include leg extensions for taller beds. Listings often reference recommended maximum gaps (e.g., no more than 1/2 inch/13 mm) to prevent entrapment—confirm attachment instructions and gap limits in the product manual.

Mattress options vary: some models include a mattress or pad (often firm foam with a waterproof, wipeable cover), while others sell the mattress separately. Care guidance in listings commonly recommends spot cleaning or wiping the cover clean.

Portability varies by model. Several listings highlight that the bassinet folds and fits into a carrying case or travel bag, some models have wheels (including lockable wheels) for room‑to‑room movement, and a few are described as easy to fold for storage or travel. Check the specific model for folding and transport features.
