Buy the Mellanni Iconic 4-Piece in Queen White (80 x 60 x 16 in fitted) if you want a stated OEKO-TEX certificate number and a lifetime return promise at $36.97; buy the CGK Unlimited 4-Piece in Queen White (01-White) if you want the same 4-piece Queen layout for $11.98 less at $24.99. Both sets cover the identical Queen checklist observed on 09/16/2026: one fitted sheet, one 102 x 90 in flat sheet and two 20 x 30 in pillowcases in double-brushed microfiber (polyester), with pockets sized for mattresses up to about 16 inches deep. The Mellanni concentrates on documented assurance: its listing names OEKO-TEX STANDARD 100 certificate 22.HUS.40891 (Hohenstein) and a Mellanni Lifetime Promise with returns any time for any reason, and its maker page confirms the 16-inch deep-pocket design with all-around elastic. The CGK concentrates on value: its title carries an Oeko-Tex claim without a certificate number in the observed pages, and its maker page confirms an 8-to-16-inch fit range with all-around elastic plus machine-wash-cold, tumble-dry-low care. On 09/16/2026 the exact Mellanni Queen White variant was In Stock on Amazon US at $36.97, sold by Mellanni with shipping from Amazon Fulfillment, and the exact CGK Queen 01-White variant was In Stock at $24.99, sold by CGK Unlimited with shipping from Amazon Fulfillment.

Mellanni Iconic Queen White: the documented-assurance pick
The Iconic 4-Piece (Queen, 1102 White) is the pick when paperwork matters. The mechanism is explicit: the fitted sheet is cut 80 x 60 x 16 in so a mattress up to 16 inches deep sits inside the pocket, sewn-in elastic keeps the corners snug, and the flat sheet (102 x 90 in) plus two 20 x 30 in pillowcases complete the bed in double-brushed microfiber. The differentiator is verifiability: the listing prints OEKO-TEX STANDARD 100 certificate 22.HUS.40891 from Hohenstein, and the maker page confirms OEKO-TEX STANDARD 100 certification, so the claim can be checked rather than taken on faith. The listing also carries the Mellanni Lifetime Promise with returns any time for any reason, and states lab breathability testing through Intertek, Hohenstein and IDFL. Its limits are price and scope: at $36.97 observed it costs $11.98 more than the CGK for the same layout, the lab and award statements (including Good Housekeeping Best Bedding) are listing claims rather than independent test results, and softness itself remains subjective. Confirm Size Queen, Color 1102 White and the 16-inch pocket option on the exact-variant page before buying.
CGK Unlimited Queen 01-White: the value pick
The Unlimited 4-Piece (Queen, 01-White) is the pick when the budget decides. The mechanism is explicit: the fitted sheet (80 x 60 in) uses all-around elastic across the maker-stated 8-to-16-inch range, the flat sheet runs 102 x 90 in, and two 20 x 30 in pillowcases finish the set in double-brushed microfiber yarns the maker describes as breathable and cooling. The listing title carries an Oeko-Tex claim and wrinkle-free wording, and care is simple: machine wash cold with like colors, tumble dry low. Its limits are documentation: no certificate number appears in the observed maker or listing pages, no lifetime promise is stated, and no lab is named, so buyers who need checkable assurance rather than a title claim should weigh that gap. At $24.99 observed it undercuts the Mellanni by $11.98 for the same four pieces in the same sizes. Confirm Size Queen, Color 01-White and Pattern Solid on the exact-variant page before buying.
Pocket depth, certification and the price gap
Day-to-day difference comes down to three things. First, fit: both sets are built around a 16-inch ceiling, but only the Mellanni prints the fitted depth as 80 x 60 x 16 in with a selectable 16-inch pocket option, while the CGK frames fit as a range (maker 8 to 16 in, listing around 16 in). On a thick pillow-top near 16 inches, the explicit Mellanni cut is the safer read; on a standard 10-to-14-inch mattress, both observed constructions fit. Second, certification: Mellanni gives a number to verify (22.HUS.40891); CGK gives a word in the title. Neither maker publishes wash-test data in the observed pages, so treat fade, shrink and wrinkle wording as care guidance plus marketing, and follow the cold-wash, low-dry instructions both makers print. Third, money: $36.97 against $24.99 on the same date, both In Stock, both sold by their brand owners with Amazon Fulfillment shipping and the same Saturday Sep 19 delivery estimate. Prices move; compare only the dated observed figures.
Warranty, returns and what it costs to own
The Mellanni assurance story is the clearer of the two in the observed pages: a stated Lifetime Promise with any-time, any-reason returns sits beside the certificate number, so the premium buys documented recourse as well as fabric. The CGK pages state no equivalent promise, which means returns fall back to the standard Amazon flow for the order. Running cost is laundry for both: cold machine wash and low tumble dry, with no filters, batteries or refills. White shows discoloration sooner than dark colors, so the care instructions matter more here than with patterned sets. At the observed prices the gap is $11.98; neither observed page ties price to a durability figure, so do not read lifespan into the price difference.
Where to check the exact variants
Compare the Mellanni Iconic 4-Piece in Queen White, 1102 White (B00NLLUMOE) (observed In Stock at $36.97 on 09/16/2026, sold by Mellanni, ships from Amazon Fulfillment) against the CGK Unlimited 4-Piece in Queen 01-White, Solid (B01M16WBW1) (observed In Stock at $24.99 on 09/16/2026, sold by CGK Unlimited, ships from Amazon Fulfillment). Size and color matter here: the Mellanni page centers Queen with a 16-inch pocket-depth option and color 1102 White among dozens of siblings, and the CGK page centers Queen with color 01-White among a numbered color range, so confirm size, color and pattern on the exact-variant page before buying. If a checkable certificate and a stated lifetime promise matter most, take the Mellanni; if the lowest observed price for the same layout matters most, take the CGK.
