Who takes it back
The retail partner that took the order. Not this catalogue, and not the manufacturer. The return window, the state the thing has to be in, and how the money comes back are all set by that retailer’s policy, which sits on the order confirmation.
There is nothing to send to the address printed on this site. It is a desk, and a parcel arriving there helps nobody.
Read the window before assembly
Baby gear tends to sit in its box for weeks, because it was bought ahead of the stage it is for. That is exactly how a return window runs out unnoticed.
A useful habit: unbox, assemble, and set the child in it once, all inside the first week. A high chair that turns out to be too tall for the table shows that in ten minutes, and ten minutes is all it takes to still have a choice.
Hygiene items are their own case
Anything that meets skin directly, a seat pad, a bath cushion, a potty seat, is often treated differently once the packaging is open. That is normal across the trade and has nothing to do with the piece being faulty.
Where a fabric cover unhooks, washing it does not un-open the box. Check the wording on the retailer’s policy first if the piece may be going back.
If the hardware itself failed
A cracked frame, a motor that stopped swinging, a harness buckle that will not latch: that is a warranty matter with Kids II, and the manual carries the terms and the model number to quote.
Stop using the piece in the meantime. A seat or a swing with a fault is not a seat or a swing with a quirk.
The short version
- The retailer who took the order sets the window and the money back.
- Assemble inside the first week, while a choice still exists.
- Skin contact items are often treated differently once opened.
- Broken hardware is a warranty matter with the maker.
