You squeeze your squishy, let go, and wait.
Sometimes it slowly returns like it has nowhere else to be. Other times, it bounces back surprisingly quickly. So, is something wrong?
Usually, no. A changing rebound speed is one of the most interesting characteristics of a slow rising squishy.
Let’s look at what is actually happening inside that soft little face.
What Makes a Squishy “Slow Rising”?
In this article, “slow rising” specifically refers to squishies made from slow-recovery polyurethane (PU) foam. This PU foamed material has viscoelastic properties that help it return gradually after being compressed.
That means it behaves partly like an elastic solid and partly like a material that relaxes gradually. When you press it, the foam cells compress and temporarily hold the new shape. After you release your hand, the structure slowly expands again.
That delayed return is what creates the satisfying slow-rise effect.
It is also why two squishies can feel completely different even when they look similar.
Temperature Changes the Rebound Speed
Temperature is one of the biggest reasons your squishy might rise at a different speed.
In a cooler room, the foam usually feels firmer and may return more slowly. In a warmer environment, the material becomes softer and often rebounds faster.
Even the warmth of your hands can make a difference. After holding and squeezing the same squishy for a while, you may notice that it feels softer or rises a little faster than it did at first.
This does not automatically mean the squishy is damaged. It is simply the foam responding to its surroundings.
For a more consistent experience, let the squishy rest at normal room temperature before comparing its rebound speed.
Foam Density and Shape Matter Too
Not every part of a squishy contains the same amount of foam.
A thick, rounded body may rise more slowly than a thin ear, tail, or decorative detail. Dense foam can also feel more resistant under your fingers, while lighter foam may compress and recover more quickly.
Paint coatings and surface finishes can slightly affect the way the outside moves as well. This is why handmade-style squishies sometimes have small differences in texture, resistance, or rebound time.
Those differences are part of their personality—not necessarily a defect.
The Way You Squeeze It Changes the Result
A quick press and a deep, full squeeze do not create the same effect.
If you gently press only the surface, the squishy has less distance to recover and may appear to rise quickly. If you slowly compress the thicker part and hold it for a moment, the foam has more time to settle into the squeezed shape.
The result is usually a more dramatic, satisfying rebound.
Try using your whole palm instead of pulling or pinching small details. Thin parts are more delicate and do not need the same pressure as the main body.
In other words: press, wait, and let the pout return on its own schedule.
Is a Slower Squishy Always Better?
Not necessarily.
Some people love extremely slow rebound because it creates a longer visual transformation. Others prefer medium resistance because it gives their hands something more noticeable to work with.
The most enjoyable squishy is the one that feels good to you.
A good slow rising squishy should recover its shape under normal use, feel pleasant to squeeze, and suit the type of resistance you enjoy. Rebound speed is only one part of the experience.
How to Care for a Slow Rising Squishy
A little care can help preserve its shape and surface:
- Keep it away from direct sunlight and strong heat.
- Avoid storing it tightly compressed for long periods.
- Press the thicker body instead of pulling small decorations.
- Keep sharp objects, rough surfaces, and pet claws away.
- Gently wipe the surface with a clean, soft, dry cloth.
- Do not use a wet cloth, wash the squishy, or soak it in water.
Some gradual surface wear can happen with repeated squeezing. Squishies are soft objects designed to be handled, so small signs of use are normal over time.
Let It Take Its Time
A slow rising squishy is supposed to make you pause.
Its rebound can change with the temperature, the structure of the foam, the shape of the character, and the way you squeeze it. Those little variations are part of what makes each squishy interesting.
So if yours seems slower today, it may simply be enjoying the weather.
No thoughts. Just squish.
