Delta Children Lee Portable Folding Mini Crib review

Delta Children’s Lee W115550 is a folding mini crib with one documented mini-crib arrangement. Its U.S. product record groups four finish SKUs under the same model family: Grey W115550-026, Bianca White W115550-130, Chestnut W115550-836 and Ebony W115550-0011. This is a source-based review of those records, not a hands-on inspection; no assembly, movement, physical measurement or mattress-fit test was performed.

A folding frame with a fixed mini footprint

Delta lists the assembled crib at 39 inches wide, 25 inches deep and 36.25 inches high. The width can be the first hard stop in a narrow room: a 38.5-inch maximum excludes it, while 39 inches is the first selectable half-inch ceiling that admits the listed frame. That is the crib’s outside product dimension, not the room area it needs. Leave separate space for doorway turns, access around the crib, nearby furniture and bringing the frame in.

The manufacturer also lists a folded envelope of 39 by 6.25 by 36.25 inches and a product weight of 29.7 pounds. Folding reduces depth, not the longest dimension; it does not make the crib a small carry-on object. Think of it as a frame that can be folded for storage or transport, not as proof that any vehicle, doorway or overnight setup will fit. Delta promotes the model for shared bedrooms and trips, but the crib still needs to be correctly re-erected before use. Confirm the exact unit’s setup and folding steps using its own manual.

What “included mattress” means here

The product page describes an included 1.5-inch mini-crib mattress and lists its dimensions as 37.5 by 23.25 by 1.5 inches. Elsewhere it says the mattress uses 24-by-38-inch sheets. Those are different figures for different things: the sheet size is not a measurement of the mattress surface. Both are maker-listed specifications, not dimensions we measured.

The exact product page links Booklet A 44786 R1, dated August 8, 2024. Its cover says “Portable Crib” and leaves the Style, Lot and Date fields blank, so the link alone does not identify the manual revision for every physical crib. The linked warnings say to use only the included mattress or one supplied by Delta Children, at least 37 inches long by 23 inches wide and no more than 2 inches thick; they also prohibit adding another mattress or soft padding. The listed included surface sits inside those stated bounds, but this is not approval of an aftermarket substitute. Check the label and supplied instructions on the actual crib, especially for used or replacement purchases.

Two support heights, not a conversion system

The page describes two mattress-support positions. It says to begin at the higher setting and lower the support as the child grows; the linked booklet specifically says to use the lowest position when the child can pull to a standing position. It says to stop crib use when the child can climb out or reaches 35 inches tall. These are the product’s cited use boundaries, not an age forecast.

Nothing in the inspected product record or page-linked instructions documents a bassinet, midi crib, full-size crib or later bed conversion. Changing support height and folding the frame are not new sleep stages. If the purchase plan requires a larger crib later, compare a system with a documented full-size crib arrangement rather than interpreting “portable” or a long product title as convertible.

Casters are useful, but their limits matter

The maker describes four wheels, and the linked booklet calls them four free casters. That supports a wheeled mini-crib setup, not a particular braking behavior. The inspected sources do not say that the casters lock or whether the assembled crib may be moved while occupied. If moving the crib is a daily requirement, ask Delta about the exact W115550 variant and follow the manual for the individual unit; do not infer a lock from the staged photograph or from the word “smooth.”

Choose by the model code, not by resemblance

Lee shares a 39-inch listed width, folding language and a mini mattress with other Delta portable cribs, but it is not model 4470 or Mia W105550. Their product IDs, manuals, package records and listed details differ. In particular, the Lee page lists a 36.25-inch height; the 4470 page lists 37.25 inches. Do not use a generic Delta “portable crib” description to order parts, a mattress or a replacement instruction booklet for another model. The maker’s finish feed groups the four Lee color SKUs without establishing a functional difference, but the photo in this review is only Grey W115550-026.

Who should keep the Lee on the list?

It is a reasonable comparison candidate when a mini crib is the intended setup, the measured layout can accommodate the 39-by-25-inch assembled footprint with access around it, and a folding frame, included mini mattress and casters are useful. It is a poor match for a strict maximum below 39 inches, a required bassinet or full-size crib stage, an included standard full-size mattress, a documented caster brake, or a shopper who needs this crib to become a later bed.

Before ordering, match the complete W115550 model and the exact finish code on the offer, then confirm the seller’s carton actually includes the manufacturer-described 1.5-inch mini mattress and four casters. Check that the manual and crib label correspond, measure the route as well as the final position, and review the seller’s return terms. For a used crib, inspect the exact unit and fasteners and obtain current instructions from the manufacturer; the narrow recall-name screen recorded for this assessment is not clearance for an individual unit. Delta states GREENGUARD Gold and JPMA/CPSC/ASTM compliance claims on its page and names New Zealand pine, poplar and TSCA-compliant engineered wood, but no independent testing or materials analysis was performed here. No exact Amazon listing was confirmed, and this review does not assign the model a retail price or stock status.
