The short version
- Typical range: £20 – £90 — see the full high chair value guide
- What decides your price: condition, and how well you evidence it in photographs
- Cost to sell here: nothing, at any price
- Category: Baby & Kids Items
Before you photograph it
Ten minutes here is worth more than anything else you will do. Buyers are deciding between your listing and someone else’s, and preparation is what visibly separates the two.
- Strip it completely and wash the tray, seat pad and every crevice. Dried food in the seams is what makes buyers walk away.
- Check the harness. A five-point harness with all straps and a working buckle is essential, and a missing crotch strap makes the chair unsafe rather than merely incomplete.
- Test the folding mechanism and every height and recline adjustment, and check the locking catches engage firmly.
The photographs that sell a high chair
Four photographs do almost all the work. Shoot in daylight, near a window, with the item against something plain — and do not use the flash, which flattens texture and hides exactly what buyers are trying to see.
- The chair set up, whole, from a three-quarter angle
- The harness laid out, showing all straps and the buckle
- The tray removed and the seat, clean, from above
- The folding catches and footprint folded, plus any crack, stain or missing part
Photograph the flaws too. It feels counterproductive, but a listing that shows the worst of an item gets fewer questions, fewer withdrawn offers and fewer arguments at handover. Buyers who can see the damage stop imagining something worse.
Writing the title and description
Brand, model and type: “Stokke Tripp Trapp High Chair with Baby Set” or “Folding High Chair, Wipe Clean, 6m+”. Named brands carry real value here and their accessories are searched separately. Say whether it folds and whether the newborn insert or harness is included.
Then state these in the description, because a buyer who has to ask is a buyer who might not bother:
- Brand, model and the age range it is designed for
- Whether the harness is five-point and complete
- Whether it folds, and the folded and assembled footprint
- What is included — tray, insert, cushion, spare covers — and any missing part
What buyers will actually ask
You will receive the same three messages about a high chair. Answering them in the listing itself removes the back-and-forth, and answering them well when they do arrive is what turns an enquiry into a sale.
Check every strap and the buckle and answer specifically. Parents will not buy a high chair with a missing strap, and replacements are often model specific and hard to source.
Photograph it clean rather than claiming it. Fabric seat pads stain permanently, so if yours is marked, show it and price it accordingly.
Give the manufacturer’s stated range, including whether it reclines for younger babies or converts for older children. Parents are buying for a specific stage.
Pricing it so it actually sells
Start from the honest condition grade rather than the price you hope for. WishThrift listings use five grades — New with Tags, Like New, Good, Fair and For Parts — and what each grade means is worth reading before you choose, because grading up is the most expensive mistake sellers make. It does not raise the price; it produces a buyer who arrives expecting something else.
The high chair value guide prices all five grades for this item. Pick your grade, take the figure, and if you sit between two grades price toward the lower one. Items priced honestly sell faster than items priced hopefully, and on a free platform there is no fee eating the difference anyway.
What you keep, compared
On a £55 sale — roughly the middle of the range for a high chair — here is what the commission-charging platforms would take, and what you would keep on each:
| Where you sell it | Fee | You keep |
|---|---|---|
| WishThrift | £0 | £55 |
| Poshmark | −£11 | £44 |
| eBay | −£7 | £48 |
| Mercari | −£6 | £49 |
| Etsy | −£4 | £51 |
Seller-side rates verified 26 Jul 2026 — Poshmark: 20% commission on sales of $15 and above; eBay: 13.6% final value fee, plus a per-order fee; Mercari: flat 10% selling fee; Etsy: 6.5% transaction fee, plus a listing fee and payment processing. Percentages are applied to the sterling figure above; the fixed per-order and processing charges those platforms add are quoted in their own currency and are not included here, so the real deductions are slightly larger. Full breakdown: marketplace selling fees compared.
Timing and getting it to the buyer
Steady all year, with a small lift in the new year. Well-known brands in clean condition sell within days because the alternative is spending several times as much new.
Folding models fit in a car easily; solid wooden chairs need a boot. Give the folded dimensions, and hand over any instruction manual, which parents genuinely use for reassembly.
WishThrift does not process payments or arrange delivery — you and the buyer agree both directly — so confirm payment has cleared before the item leaves your hands, and keep the conversation on the site so there is a record of what was agreed.

Frequently asked questions
What is a used high chair worth?
Typically £20 to £90, with premium convertible brands well above. See the high chair value guide for pricing by condition.
Can I sell a high chair with a missing harness strap?
You should not sell it as usable. The harness is the safety component, and a chair missing part of it is not safe for a child. Source a genuine replacement first, or sell it clearly as spares.
Do second-hand high chairs need to meet a safety standard?
Chairs sold new must meet the applicable standard, and yours will carry a marking if it did. Quote the standard from the label if it is there, and never sell a chair with cracked plastic or a failed locking catch.
