Fisher-Price Deluxe Sit-Me-Up Floor Seat with Toy Tray, Happy Hills (GBL20)

A stable folding floor seat with trays, useful for a short stage and only on the floor.

The short version

Buy it if
  • Parents of babies who hold their head up well but still need help sitting
  • Families who want a seat they can fold flat and carry between rooms or homes
  • Anyone who wants a tray for snacks and toys while the baby sits on the floor
Skip it if
  • Your baby can already sit or crawl out on their own
  • You want something to use on a table, sofa or bed; the maker says floor only
  • Your baby has very full thighs and you want easy in and out

What owners like

  • Folds small, which makes it easy to store or bring to a relative's house
  • Wide base feels stable on the floor
  • Washable pad makes clean up simple
  • Leg openings are larger than on a molded foam seat, so it suits bigger babies longer

Common complaints

  • Lifting a baby with chunky thighs in or out can be awkward
  • Short useful life, since it is meant only until a baby can climb out or walk
  • The frame is hard to take apart once assembled, according to one owner

Based on The Fisher-Price support page and instruction sheet for GBL20, the Amazon listing, Babylist's page for the closely related basic Sit-Me-Up seat, ChickAdvisor owner reviews of the Sit-Me-Up line, and a parent blog comparing the Sit-Me-Up with the Bumbo..

What it does

A folding floor seat that holds a baby upright on the floor, with a removable snack tray and a clip-on toy tray, in the Happy Hills print.

  • Wide base meant to hold an unsteady sitter upright on the floor
  • Removable snack tray that is top rack dishwasher safe
  • Toy tray with bat-at spinners, clacker beads and a teether ring that lifts out of the snack tray
  • Seat pad comes off and is machine washable on a cold, gentle cycle
  • Frame folds flat for storage or travel
  • Adult assembly with no tools

A reasonable pick for parents who want a supported floor seat with a tray for babies who already hold their head up but cannot sit alone yet. The trade-offs are a short window of use, ending once the child can climb out or walk, and reports that babies with chunky thighs can be hard to lift in and out.
