Chicco Stack Hi-Lo High Chair
Five real stages plus a two-at-once combo counted as the sixth — the same mode math as the Graco Blossom (#185) at a third of its price: a sturdy reclining high chair/booster/stool system to 100 lb, but with no height adjustment, footrest, wheels or fold, and a seat owners call small for larger babies.

6-in-1 from infancy to big kid, seats two at once in combo mode, 3-position recline, machine-washable pad, stool to 100 lb
The catch
the 6th “mode” is the other five reused two-at-once; no height adjustment, footrest, wheels or fold; seat runs small; the manual says spot-clean the pad the marketing calls machine-washable

What it is
A convertible high chair system — pinned here as the Sand colourway, model 05087134870070, Amazon ASIN B0CBL6R2W3 (Tide is the other colourway in retailer records, model 07087134810070; same chair). A padded seat base + backrest sits on a youth stool base with metal legs; the seat lifts off to become a chair booster while the base becomes a stool. Assembled 22 × 28 × 43 in. Weight is reported two ways in the records — 16 lb as the Amazon item weight (Ubuy’s Amazon-mirror record) and 21 lb in the brand datasheet; either way reviewers call the metal frame heavier to shift than all-plastic rivals, and it moves on easy-glide feet, not wheels. The six named configurations: (1) High Chair — sit-upright babies to 36 months or 40 lb, 5-point harness, 3-position recline with one-hand adjustment, snap-on tray adjustable to 3 positions with a removable liner; (2) Chair Booster — the seat strapped to a dining chair (seat at least 15 in wide × 14 in deep, backrest at least 12 in high), with or without the tray, to 50 lb; (3) Low Chair — bottom leg extensions removed for low snacking/play seating; (4) Toddler Chair — the shortened-leg first chair; (5) Youth Stool — contoured stool seat with a pop-up backrest and two height adjustments, for age 3+ to 100 lb; (6) Booster + Stool Combo — (2) and (5) occupied simultaneously by two children. Leg extensions snap into the base for storage and the tray stores on the rear legs. There is no height adjustment for table fit (the “Hi-Lo” is the removable leg extensions, not a lifting seat), no adjustable footrest in the manual or feature lists, and no fold — the 22 × 28 in footprint stays out.
Claims vs. reality
“6-in-1” — FIVE STAGES PLUS A COMBO, BY THE BRAND’S OWN WORDS. Chicco’s copy states it plainly: the chair grows “through five growth stages plus a bonus combo configuration.” Counted honestly, modes 1–5 are sequential lives for one child, and two of them (low chair vs. toddler chair) differ mainly by the same leg-extension removal. Mode 6 is not a sixth seat — it is modes 2 and 5 used at once. That is still the chair’s best trick (a baby in the booster, a big kid on the stool, one purchase), and hands-on review video confirms the frame held two children without wobbling — but it is the same mode-count arithmetic as the Graco Blossom 6-in-1 (check #185), whose sixth mode is likewise “seat 2 kids at once.” The pattern is category-wide: the number counts simultaneous reuse, not extra hardware. Buy either chair for the five stages you will actually use, not the six on the box.
“Grows from infancy” — FROM SITTING UP, NOT FROM NEWBORN. The manual recommends the high chair “only by children capable of sitting upright unassisted,” caps high chair mode at 36 months or 40 lb, and restricts booster mode to the upright position only — “Do not recline the back in booster seat mode” (the 3-position recline is a high-chair-mode feature). The youth stool is age 3 and up. So the honest span is roughly ~6 months to a 100 lb big kid, in stages — long, but it starts at solids, not at birth, and no stage reclines a newborn flat.
“Easy-clean / machine-washable pad” — THE MARKETING AND THE MANUAL DISAGREE; THE MANUAL GOVERNS CARE. Retailer and brand copy promise a “wipeable, machine-washable seat pad” and a dishwasher-safe tray liner; Zola’s registry record reduces care to “Wipe clean.” The owner’s manual’s Cleaning section says: “You can spot clean the seat pad with a damp cloth and mild detergent. Do not use bleach, spray, or wipes on the Pad or plastics parts,” and defers fabric care to the care label. The tray liner does lift off for washing (manual steps 21–23), which is the daily win owners praise. Treat “machine-washable” as a care-label question on your unit, not a listing promise — and note the owner asterisk that dried food works into the tray liner’s edges and needs periodic deep cleaning.
“Eco-friendly fabric” — TRACES TO THE LISTING, NOT TO A CERTIFICATION. The Amazon listing copy (via Ubuy’s mirror record) states the “main fabrics are made from recycled PET bottles.” No percentage, certifier or standard (no GRS, OEKO-TEX or GREENGUARD claim) appears in the brand datasheet, manual or retailer records consulted — so the check records it as an unquantified listing claim: plausible, directionally nice, and not a verified certification of the kind check #195’s OEKO-TEX Class 1 is.
What “6-in-1” leaves out — THE FIT FEATURES. Against the Blossom’s 6 height positions, 3-position footrest and locking casters, the Hi-Lo offers none of the three: one fixed high-chair height, no footrest to support dangling feet (the manual’s parts list has no footrest component), glide feet instead of wheels, and no fold for storage. Its compensations are price (half the Blossom’s $239.99 at the pinned street figure, and below it even at MSRP), the 100 lb stool rating (Blossom youth seating caps lower in Graco’s records), and a smaller, lighter system. Whether that trade is smart depends entirely on which list your kitchen needs.
The size owners flag — A SMALL SEAT UNDER A BIG NUMBER. The most specific critical review in the file (Target, syndicated from chiccousa.com, Feb 23, 2024) warns the seating area is “very small… If you have a chubby baby you might want to look elsewhere,” with few tray positions to compensate, a pad material that is “durable yet rough” against the baby’s head, and booster attachment straps that are hard to access (her husband nearly broke the compartment forcing it open). Ubuy’s Amazon-review synthesis adds: the chair may tip slightly if unbalanced (e.g., loaded tray, no child seated), the tray attachment is stiff at first, and recline travel is limited. None of this contradicts the 40 lb high-chair rating — it means bigger babies can age out of the fit before the limit.
Safety & recalls
No CPSC recall for the Chicco Stack Hi-Lo was found Oct 23, 2026. Do not confuse it with the 2012 CPSC recall of ~455,000 Chicco Polly high chairs (pre-Oct 2010 manufacture; children were bruised and cut falling onto the tray-storage pegs on the Polly’s rear legs) — a different, discontinued model; the Hi-Lo is not named in that recall, though it coincidentally also stores its tray on its rear legs, which is exactly why the distinction is stated here. The manual’s own warnings are the operative safety record: FALL HAZARD — children have suffered severe head injuries including skull fractures falling from high chairs; always use the restraint snugly, in reclined and upright positions alike; the tray is not designed to hold the child in the chair; stay near and never leave the child unattended; never use high chair mode without the backrest attached; place only on a horizontal, stable surface and never move it with the child in it. Booster mode: secure with both attachment straps to a full-size dining chair only — never folding chairs, pedestal chairs, bar stools or any other elevated surface; check the attachment before each use; never lift or carry the child in the booster. Youth stool/toddler chair: age 3+, 100 lb maximum. Secondhand units: verify every leg pin engages, both booster straps and compartments are intact, the harness buckles and the tray snap on securely, and check the model on SaferProducts.gov.
Real reviews — what owners say
Amazon (this ASIN, Sand): pricehistory.app records 8.8/10 across 144 reviews — that score is the tracker’s own /10 scale, cited here as the review count with its source named; Ubuy’s Amazon-mirror record shows 4.6/5 across 123 customer ratings (82% five-star) for the same listing family. The file is small — there is no BabyGearLab lab test of this model in the records consulted, and Target’s page carries brand-syndicated reviews rather than a large independent count — so this check leans on the manual and brand records more, and on owner evidence less, than most in the library. What owners praise is consistent: tool-free assembly in minutes (“put it together in literally 5 minutes”), a sturdy, stable metal frame, the one-hand recline and snap-on tray, the lift-off tray liner that makes daily cleanup genuinely easy, and the versatility itself — launch-cluster reviews on Target/chiccousa.com call it “the ‘Transformer’ of high chairs” (several of those July 2023 five-star reviews were written on arrival, before sustained use, as the critical reviewer in the same file points out). The complaints are equally consistent and are carried in Claims: small seat for larger babies, rough pad texture, hard-to-open booster strap compartments, a stiff-then-loosening tray, slight tipping when unbalanced and unoccupied, food trapping at the tray liner’s edges, and a heavier carry than all-plastic chairs. No structural-failure pattern appears in the file.
Price & FSA/HSA
$74.99 is the pinned price — pricehistory.app’s current US figure for ASIN B0CBL6R2W3 (Sand), read Oct 23, 2026, independently matched by Albee Baby’s InStock offer for the same Sand chair at $74.99; the card links Amazon with the Associates tag. The candidates file flagged this record for variant-artifact risk because its tracked history swings widely — average $99.00, high print $209.99 across ~1,191 days of tracking — and the staging resolution is stated, not hidden: the $74.99 figure is corroborated by a second retailer for the pinned variant, while the brand MSRP is $149.99 (brand datasheets for both colourways), so treat $74.99 as a street price at its tracked low, not the chair’s normal price — at $149.99 the verdict’s math tightens considerably. No consumables and no required extras; the tray, liner, pad and harness are all in the box. The ladder: down — IKEA ANTILOP, $19.99 IKEA-direct (no recline, no conversion; not an Amazon product) and Chicco’s own Zest 4-in-1, $69.99 at Target (folds, fewer stages); sideways in this slate — check #185’s Graco Blossom 6-in-1, $239.99 (the same 5+combo counting, plus 6 heights, an adjustable footrest and casters the Hi-Lo lacks); checked already — Abiie Beyond Junior Y (check #121), $229.95–$238, the wooden grow-to-adult route. FSA/HSA: not eligible — a high chair is general baby furniture/feeding gear, not medical care.
The second “6-in-1” chair in this slate — and the mode count inflates the same way the Graco Blossom’s does (check #185). Chicco’s own copy gives the game away: five growth stages plus a bonus combo. The five are real seats used one at a time (high chair, chair booster, low chair, toddler chair, youth stool); the sixth is using the booster and the stool at the same time for two kids — a genuine trick, but a reuse of the same parts, not a sixth product. What you actually get for the money is a solid high chair with a 3-position one-hand recline, padded 5-point harness and a snap-on tray with a removable liner, on a sturdy metal frame rated to 100 lb in stool mode — with no height adjustment, no adjustable footrest, no wheels and no fold, and a seat owners repeatedly call small for larger babies. At the pinned $74.99 street price — half the $149.99 MSRP — that trade can pay. At list price, against chairs that do adjust, it does not.
