A useful fit for

A plausible document-based shortlist for someone seeking a maker-documented full-size crib with a listed 30-inch width and later toddler-bed, daybed and sofa arrangements. Confirm the exact finish SKU, dimensions, mattress and both the conversion-rail and color-specific toddler-guardrail contents before purchase.

The main tradeoff

The standard full-size mattress and toddler guardrail are separate; W173726 is listed for Acorn while W173727 is listed for Antique White. The linked Booklet A identifies Acorn style 45751 and W173726, so its applicability and exact parts for Antique White must be checked against the frame label and supplied instructions. Dimensions are product measurements, not room clearance, and no hands-on evaluation was performed.

Your needs, this model

Does it fit your priorities?

Which Wren finish reaches the 30-inch listed-width ceiling?

Both observed variants—Acorn W137630-755 and Antique White W137130-1545—are listed at 30 inches wide, 34.25 inches high and 54.25 inches deep. Both first meet a 30-inch half-inch-grid ceiling, not 29.5. This compares Delta's frame width only; measure room and conversion clearance separately.

What exact toddler rail is needed for each Wren finish?

Delta names W173726 for Acorn W137630-755 and W173727 for Antique White W137130-1545, and sells these guardrails separately. The linked Booklet A cover is style 45751/R0 and its toddler-bed page specifies W173726 only; confirm the W137130-1545 frame label and supplied manual rather than assuming the two rails interchange.

What mattress and crib-use limits does the linked Wren booklet state?

The standard full-size crib mattress is sold separately. The booklet requires at least 27 1/4 by 51 5/8 inches and at most 6 inches thick, specifies three support positions, calls for the lowest position once a child can pull to standing, and stops crib use at climbing or 35 inches tall, whichever comes first. At the highest setting, the front side must remain at least 3 inches above the mattress. The booklet gives a 15-month minimum age and 50-pound maximum for toddler-bed use; match it to the exact frame.

This document-based assessment covers the two exact babyGap Wren variants observed in Delta Children’s U.S. crib collection: Acorn W137630-755 and Antique White W137130-1545. The shared model page describes a full-size crib with toddler-bed, daybed and sofa arrangements. I did not assemble, own, measure or test the crib; dimensions, package details and safety directions below are attributed to Delta’s pages and linked instructions.

Two finishes, one full-size footprint

Delta’s collection record and selected-variant pages identify Acorn W137630-755 (UPC 080213161569) and Antique White W137130-1545 (UPC 080213161477) under one Wren product ID. Both pages list the same assembled dimensions—30 inches wide by 34.25 inches high by 54.25 inches deep—and product weight of 47.4 pounds. The captured evidence does not establish a structural or dimension difference between finishes. The color-coded toddler guardrail is a real variant distinction: the Acorn page names W173726, while the Antique White page names W173727. Keep the full suffix, finish and UPC with the crib rather than treating the two boxed variants as interchangeable.

The finder uses the manufacturer’s 30-inch width field. Wren is excluded at a 29.5-inch maximum and first qualifies at 30 inches, when the shopper also selects a full-size crib and requires that stage. That single product-width number is not room clearance. Measure the path through doors and the space needed to assemble and later reconfigure the frame; Delta’s listed depth and height matter too. The exact product page lists New Zealand pine and TSCA-compliant engineered wood, and states GREENGUARD Gold and JPMA claims. These are maker descriptions, not independent material or emissions tests performed for this review.

What “4-in-1” covers—and what it does not

Delta describes successive full-size crib, toddler-bed, daybed and sofa layouts. Those are reassembled modes, not simultaneous sleeping areas or a change to a smaller crib size. The product pages describe the mattress-support as three-position, but no mini crib, midi crib or bassinet arrangement is established. Nor do the inspected pages document an adult full-size-bed conversion. A shopper seeking a small early sleep surface, wheels or a later adult bed should compare another documented system rather than infer those features from the stage count.

The standard full-size crib mattress is sold separately. The linked U.S. booklet specifies a mattress at least 27 1/4 by 51 5/8 inches and no more than 6 inches thick. That is a manufacturer fit limit, not evidence that a particular mattress is included or fits an unexamined frame. Do not add extra padding; use the actual Wren instructions and mattress label when checking the sleeping surface.

Separate the two kinds of rail—and check the edition

The linked Wren booklet’s component list identifies conversion rail style 45750 and its later-layout instructions say that rail is needed for the specified toddler/daybed/sofa arrangements. Separately, Delta lists toddler guardrails by finish: W173726 for Acorn and W173727 for Antique White. These are separate part numbers and the manual does not establish that one finish rail fits the other. Before buying a new package, verify its written contents; before buying used or open-box, check the crib-end label, finish, fasteners, rail numbers and instructions rather than assuming a conversion part stayed with the frame.

There is a specific booklet bridge to resolve for the Antique White version. The selected Acorn page links a PDF whose cover says style 45751, revision R0, dated July 18, 2024; the instructions ask the owner to compare style, lot and date to the label on the crib end. The PDF metadata title contains a different style/date string, and its toddler-guardrail page names W173726, while Delta’s exact Antique White page and accessory page name W173727. This assessment retains that mismatch instead of guessing whether the shared file applies identically to both finishes. Match the manual supplied with your exact W137130-1545 frame and ask Delta to resolve any conflict before conversion.

Use the manual limits as decision points

The Wren booklet gives three support positions. It says to use the highest only while the baby is very small and requires the front rail to remain at least three inches above the mattress when both support and mattress are at the top; otherwise, lower the support. Once a child can pull to standing, set the support at its lowest position. Stop crib use when the child begins to climb out or reaches 35 inches tall, whichever comes first. These setup and stop directions are more useful to a household than an unqualified promise of four long-lasting stages.

For toddler-bed use the booklet sets a 15-month minimum age and a 50-pound maximum weight. Follow all warnings, fastener checks and conversion steps in the exact manual; this article is not a substitute for them. Delta’s narrow SaferProducts.gov searches for W137630 and W137130 returned empty arrays, but those keyword queries do not establish a unit, lot, serial-number, repair or used-item safety clearance.

Who should shortlist Wren?

Wren is a plausible paper-fit option for someone who wants a 30-inch-listed-width full-size crib, likes its restrained slatted design, and is willing to buy the mattress separately and verify the later-mode hardware. Its matching width across the two captured finishes simplifies room comparison, while the color-specific toddler-rail codes make exact identification essential. The open-side modes require a careful parts and manual check, particularly for Antique White. A buyer with a sub-30-inch maximum, a need for wheels or a smaller first configuration, an included mattress requirement, or a firm preference for an unambiguous all-variant booklet trail should pause and compare alternatives. Check the exact SKU on the retail offer, the included 45750 rail statement, the matching W173726 or W173727 guardrail, mattress dimensions, footprint, return terms and version-specific instructions before deciding.
