A toy box is a great way to keep a child’s room neat and organized, but a heavy lid can quickly become a safety hazard. A lid that slams shut may pinch little fingers, create loud noises, or even damage the toy box over time.
Apexstone Soft Close Hinges are designed to solve this problem. Powered by an integrated soft-close gas strut mechanism, they slow the lid before it closes, providing smooth, controlled movement without sudden slamming. Unlike traditional lid supports, these hinges are designed specifically for soft closing and do not hold the lid open.
In this guide, we’ll show you exactly how to install soft close hinges on a toy box, how to choose the correct quantity, and how to avoid common installation mistakes.
Why Install Soft Close Hinges on a Toy Box?
Installing soft close hinges offers several important benefits for both children and parents.
Protect Little Fingers
A slow, controlled closing motion helps reduce the risk of pinched fingers by preventing the lid from slamming shut unexpectedly.
Quiet Closing
No more loud bangs every time the toy box is closed. Soft-close hinges make every closing motion smooth and quiet.
Extend the Life of Your Toy Box
Repeated impacts from a heavy lid can loosen screws, damage hinges, or crack wooden toy boxes. Soft closing helps reduce wear over time.
Easy Upgrade
Most wooden toy boxes can be upgraded without replacing the existing box, making installation simple and cost-effective.

How Many Hinges Do You Need?
The number of hinges depends on the lid weight.
| Lid Weight | Recommended Quantity |
|---|---|
| Up to 30 lb | 1 Soft Close Hinge |
| 30–70 lb | 2 Soft Close Hinges |
If you’re unsure, installing two hinges provides the smoothest and most balanced soft-close performance.
Step 1 – Locate the Mounting Points
Start by locating the lower mounting point. This determines the position of the entire hinge system.
For Flat Toy Box Lids
Position the lower mounting point approximately:
- 2.75 inches from the back edge
- 9 inches below the top edge
Next, fully extend the hinge’s soft-close mechanism to locate the upper mounting point.
The upper mounting point is typically positioned about 4 inches above the bottom edge of the lid.

For Deep Toy Box Lids
If your toy box has a deep lid profile, adjust the mounting position to avoid interference during operation.
Measure the lid depth and refer to it as X.
Position the lower mounting point:
- (2.75 + X) inches from the back edge
- (9 − X) inches below the top edge
Fully extend the soft-close mechanism to locate the upper mounting point.
The upper mounting point is generally positioned about 4 inches above the bottom edge of the lid.

Tip: Install one screw per bracket first. This allows easy adjustment before permanently securing the brackets.
Step 2 – Install the Mounting Brackets
Align the center of each mounting bracket with the marked mounting point.
Secure each bracket using one screw initially.
Once you’ve confirmed the hinge operates correctly, install the remaining screws to permanently secure both brackets.
Step 3 – Attach the Soft Close Hinges
Snap each end of the hinge onto the ball studs of the mounting brackets.
Apply gentle pressure until you hear a distinct click, indicating the connection is fully engaged.
Take your time to align the hinge correctly before forcing the connection.

Step 4 – Test the Soft-Close Performance
Open and close the lid several times.
The lid should close smoothly and quietly without slamming.
If the lid still closes too quickly, install a second hinge on the opposite side if the lid weight falls within the recommended range.
Once you’re satisfied with the performance, tighten all mounting screws securely.
Common Installation Mistakes
Avoid these common mistakes during installation.
Mounting the Brackets Too High
Incorrect bracket placement may reduce the effectiveness of the soft-close mechanism.
Always follow the recommended mounting dimensions.
Tightening Every Screw Before Testing
Only install one screw per bracket during the initial setup.
This allows you to make small adjustments if necessary.
Using Only One Hinge on a Heavy Lid
Heavier lids require two hinges for balanced, reliable soft closing.
Using only one hinge may reduce performance.
Skipping the Final Test
Always test the lid several times before completing the installation.
Small adjustments can make a significant difference in soft-close performance.
