Juliette 6-in-1 Convertible Crib review

This is a source-based assessment of the Simmons Kids Juliette W347150, not a hands-on review. Delta's current U.S. Cribs collection record identifies Bianca White W347150-130. A separate Delta listing identifies Moonstruck Grey W347150-1351; its captured product data was unavailable and tagged discontinued on November 1, 2026, so that is not a claim about stock elsewhere. The two listings share the W347150 style, documented dimensions, six arrangements and linked manual family. They are retained as exact finish records within one functional review.

Six sequential arrangements—not six cribs

Delta describes a full-size crib, toddler bed, daybed, sofa and adult full-size bed. Its sixth named arrangement is the adult bed built with a headboard only rather than both a headboard and footboard. These are separate reconfigurations of one furniture system, not six sleeping surfaces available at once. The product page describes its daybed/sofa/toddler guardrail kit as included; the linked booklets list separate conversion and toddler rails. I did not inspect a retail carton or seller bundle, so confirm the exact parts in the actual offer before counting on the kit.

The adult-bed route is a notable differentiator, but it brings another purchase and compatibility check. The booklets specify style 0050 conversion rails for the headboard-and-footboard arrangement and say the rail system is not included. Delta's product page also mentions metal frame #0040 for a headboard-only setup. That claim needs care: Booklet A includes a #0040 alternative on page 45, while the inspected Booklets C and D omit it. Confirm the manual revision, crib-end label, and frame instructions supplied with the actual unit before ordering a #0040 frame; do not treat a product-page mention as universal compatibility. Delta's separate 0050 rail listing also directs buyers to the exact crib manual, rather than claiming the accessory is a universal fit.

Make room around the listed footprint

Delta lists the assembled full-size crib at 56.75 inches wide, 46 inches high and 32 inches deep, with a product weight of 82.25 pounds. It lists a separate shipping carton at 42.5 by 7.1 by 60.75 inches and 96.8 pounds. The product width is not room clearance, doorway access, assembly workspace or space for later rail changes. On this finder's half-inch input, a 56.5-inch maximum excludes Juliette and 57 inches is the first selectable product-width ceiling that admits it. Measure the whole route and installed area separately, including any future bed arrangement.

The proportions and trim are visible in Delta's Bianca White manufacturer image; that image is not evidence of what a seller will include. Another exact W347150-1351 image is saved for the Moonstruck Grey listing, but the photo itself does not establish availability. A mattress shown in staged product photography is not proof that a mattress ships in the box.

Mattress fit and crib-use limits

The selected W347150 product page says a standard-size crib mattress is sold separately. All three inspected W347150 booklets specify a minimum mattress footprint of 27 1/4 by 51 5/8 inches and a maximum thickness of 6 inches. Match the exact mattress to those manual limits; they describe fit, not package contents. Delta lists three mattress-support positions. The instructions require lowering the support when a child can pull to standing and say that, at the highest support position, the front rail must stay at least three inches above the mattress surface. Stop using the crib when the child begins climbing out or reaches 35 inches tall, whichever happens first. Follow the supplied manual rather than generalizing from a conversion label.

For toddler-bed mode the booklets set a minimum age of 15 months and a maximum user weight of 50 pounds, and warn about entrapment openings and following the assembly directions. The correct toddler guardrail and conversion rail are model parts, not interchangeable décor. Keep the infant-crib stop conditions separate from toddler-bed eligibility.

Edition and parts checks matter

The current product page linked three 48-page W347150 booklets: 41177 Booklet A, revision R0 dated August 10, 2020; 42305 Booklet C, revision R0 dated August 5, 2021; and 44646 Booklet D, revision R0 dated June 23, 2021. Their key mattress, age/weight, support and use-stop warnings agree, but the parts lists are not identical. For example, the back rails are 41166, 41816 and 44635 respectively, while the headboard/cap parts also differ. The toddler guardrail/conversion components are similar in role but part identifiers likewise vary. Match the manual and parts diagram to the label on the exact crib; avoid ordering by a generic Juliette name or by finish alone.

The page attributes New Zealand pine, poplar and TSCA-compliant engineered wood to the construction and describes GREENGUARD Gold certification and testing for lead and other toxic elements. Those are manufacturer statements, not independent material or emissions testing in this assessment. A narrow SaferProducts.gov query for Juliette/W347150 returned an empty array. A keyword query is not a unit, lot or serial-number clearance, and does not replace checking the actual crib's label, condition, hardware, recall history and instructions—especially for a used or open-box item.

Who should compare the Juliette?

Juliette is a documented candidate for a household seeking a full-size crib, several later reconfigurations including adult full-size bed mode, and enough space for a listed 56.75-inch frame. It is a poor fit when an included standard crib mattress, a mini/midi/bassinet stage, or documented wheels in the selected mode are essential. Budget for a mattress and adult bed rails, verify any advertised included toddler/daybed/sofa pieces in the specific package, and resolve the manual/#0040 difference before using a headboard-only adult-bed setup. Do not read “6-in-1” as a promise that every accessory is in a seller's box or fits every W347150 booklet.

Before purchase, check the exact SKU and finish, crib-end label, booklet number, mattress limits, included fasteners and rails, delivery path, condition and return terms. This assessment reports published evidence only: it does not claim assembly, ownership, personal measurement, child use or physical testing.
