About Sassy Stacks of Circles Stacking Ring STEM Learning Toy, Age 6+ Months, Multi, 9 Piece Set
A stacking-ring toy is one of the first "engineering" toys a baby encounters. Picking up a ring, orienting it, and threading it onto a post builds hand-eye coordination and fine motor control, while pulling the whole stack apart and starting over teaches early cause and effect. It's a toy babies return to again and again between sitting-up age and toddlerhood, because the challenge grows with them.
What sets Sassy's version apart from a typical tapered-cone stacker is the straight center post: every ring has the same size center opening, so a baby can drop any ring on in any order and still get a satisfying result, instead of getting stuck because they grabbed the wrong size first. The nine pieces also vary in color, texture, and weight, one ring is filled with loose beads that rattle when shaken, and each ring is numbered to introduce counting alongside the stacking play.
It's the right fit for a baby starting around 6 months who is sitting up (independently or with support) and beginning to reach and grasp with intention, through toddlers who are still stacking and sorting past their first birthday. At the youngest end of that range, expect a baby to manage mostly the smaller top rings at first and grow into the larger bottom ones as their grip strengthens. This is a supervised floor-or-lap toy, not something to leave with an unattended infant.

The Honest Take
What We Like and What We Don't
What we like
- Nine different textures, weights, and colors keep sensory-driven babies engaged longer than a single-material stacker
- The straight-post design means any ring fits in any order, so even a 6-month-old gets an immediate stacking success instead of a frustrating size-matching puzzle
- Small extra layers beyond basic stacking: numbered rings for early counting, plus one bead-filled ring that rattles
- Genuinely durable, one long-time reviewer's original set held up well enough after 5 years that they bought a second set for a new baby
- Backed by a very large, overwhelmingly positive review base and a best-seller badge in its category
What holds it back
- Smaller than many parents expect; one reviewer noted the base fits in the palm of a hand, so this is not a large floor toy
- The base and rings are hard plastic, so if a baby topples backward onto it during play it can hurt, worth keeping clear of a baby who is still unsteady sitting or standing
- At exactly 6 months, a baby may only manage the smaller top rings at first and mostly ignore the bigger bottom ones until grip strength catches up
Is This For You?
Who Should (and Shouldn't) Buy This
Get it if…
you want a genuinely durable, sensory-rich first stacking toy that a 6-month-old can succeed with right away, without needing to match rings to a tapered peg in size order.
Skip it if…
you're picturing a large floor toy, since the assembled set is small enough to fit in one hand.
The verdict
The Sassy Stacks of Circles earns its bestseller status honestly. It's a simple, well-made stacking toy that gives babies a low-frustration win thanks to the straight-post design, and the mix of textures, colors, numbers, and a rattly bead ring gives it more to explore than a plain set of stacking cups. It isn't a large toy, and it isn't a toy for an unsupervised baby, but it earns repeat play from 6 months through toddlerhood, and it holds up well enough that parents are buying a second set years later for a younger sibling.
What Real Buyers Say
“These are a great learning toy. We bought one set for our son when he was born 5 years ago and it still holds up. But we wanted to get a new set for our little girl so they each have their own to play with. Good quality and variety of colors, textures and sizes. I will say to keep an eye on your little one if they are playing in a play pen with this, as if they fall backwards onto it, it can hurt since some of the circles and the base are hard.”
United States
“We got the Sassy Stacks of Circles for our 6-month-old, and she absolutely loves playing with them! Right now, her fine motor skills allow her to successfully pick up and manage the top 5 smaller rings. Her absolute favorite is the ring filled with little beads that makes a rattling noise. It's durable, has amazing colors and textures, and provides so many different ways for a baby to explore.”
United States
“Fun OT activity for kids. Rings are different colors, sizes, and textures so it's fun to play with and works on fine motor skills and sensory development. I would just note that it's much smaller than I anticipated. The base fits in the palm of your hand.”

Frequently Asked Questions
What age is the Sassy Stacks of Circles designed for?
The manufacturer recommends it for babies 6 to 24 months old. At the youngest end of that range, babies typically manage the smaller top rings first and grow into stacking the larger bottom rings as their grip and coordination develop.
Is the Sassy Stacks of Circles good for teething babies?
Yes. It's made from BPA-free plastic and the rings come in a range of textures meant to be mouthed and chewed, which many parents say makes it a favorite during the teething stage. As with any toy that has smaller pieces, active supervision during play is still recommended.
How is this different from a regular stacking ring tower?
Most stacking towers use a tapered post, so rings only fit in size order and a baby can get stuck if they grab the wrong one first. This set uses a straight post with rings whose centers are all the same size, so any ring fits in any order, which means a baby succeeds at stacking right away instead of getting frustrated.
