4moms mamaRoo Sleep Bassinet: Legacy Source Record
Identity correction and source record
No commerce or product recommendation
This is a noncommerce legacy-product source synthesis, not a hands-on test. The commerce identity decision is recorded in an internal dated receipt, not exposed as a public buying or evidence link. This page contains no offer, price, availability, or affiliate link.
What the evidence supports
The 4moms mamaRoo Sleep Bassinet model 1040 is documented in an official manual and fact sheet, but it is no longer presented as a current bassinet in UPPAbaby's at-home lineup. UPPAbaby acquired 4moms and continues support resources while showing a separate legacy 4moms collection. The old site ASIN B08BXRF96W resolves to a mamaRoo Sleep storage basket, not the bassinet. This page is retained to correct the identity and summarize the legacy manual without guessing at a replacement offer.
What model 1040 documented
The official manual identifies model 1040 and documents five motion patterns, multiple speed settings, vibration, sounds, a timer, Bluetooth control, a firm sleep surface, and two height positions. The manual—not an old retailer page—is the authority for assembly, warnings, stop-use conditions, and cleaning. The old copy's bedside-mode claim is removed because height adjustment does not itself establish a bedside-sleeper mode.
Why this is now noncommerce
The required Creators refresh returned a low-priced offer because the stored ASIN belongs to the accessory storage basket. Linking that offer from a bassinet review would be an identity and affiliate-integrity failure. UPPAbaby's current at-home lineup and support structure also support treating model 1040 as legacy unless the manufacturer publishes a current exact product and authorized offer.
Setup boundary
Do not add aftermarket pads, positioners, wedges, or other sleep-surface layers. Use only the mattress and fitted sheet allowed by the model 1040 instructions. Archived feature descriptions do not override current safe-sleep guidance or the manual for the unit in hand.
