How To Lower School Tables
Adjustable school tables play a vital role in providing ergonomic comfort and learning efficiency for students of different ages. Over time, teachers or facility managers may need to lower the height of school tables to fit younger students, improve posture, or adapt to a new classroom layout.
In this guide, Aoyasi Furniture Co., Ltd., a leading manufacturer of School Desks and chairs, explains safe and effective ways to adjust table height while maintaining stability and durability.
1. Understand the Table Type
Before making any adjustment, identify the type of school table you have. The mechanism determines how you can lower it safely.
Fixed-Height Tables:
These tables are welded or bolted at a permanent height. Lowering them requires re-drilling, shortening the legs, or replacing the frame — usually done by maintenance staff or manufacturers.Adjustable-Height Tables:
Most modern classroom tables are designed with adjustable legs or brackets, making them easy to modify without complex tools. Aoyasi offers several models with screw-lock, telescopic, or bolt-adjustment systems for convenient height regulation.Combination Desk Units:
These include a connected table and chair structure. The desk’s height can often be modified using the same adjustment mechanism as the chair.
2. Measure the Target Height
The correct table height depends on the students’ age and chair height. A mismatch can cause fatigue and poor posture.
| Age Group | Recommended Table Height | Recommended Chair Height |
|---|---|---|
| Kindergarten | 460–520 mm | 260–300 mm |
| Primary School | 580–640 mm | 340–380 mm |
| Middle School | 660–720 mm | 400–440 mm |
| High School | 720–760 mm | 440–460 mm |
Measure the current table height from the floor to the tabletop surface. Subtract the difference between the current and target height to determine how much you need to lower it.
3. Lowering Adjustable-Height School Tables
Step 1 – Prepare the Tools
Gather the necessary tools such as a wrench, Allen key, or screwdriver depending on your table’s design. Always work on a flat surface to keep the table stable during adjustment.
Step 2 – Loosen the Fasteners
For telescopic or screw-lock legs, loosen the locking bolts or knobs on all four legs. Avoid removing them completely to prevent misalignment.
Step 3 – Slide the Legs Downward
Gently slide the inner leg tubes downward to the desired level. Ensure all legs are adjusted evenly to prevent wobbling.
Step 4 – Secure the Locks
Retighten the screws or knobs firmly once the correct height is reached. Test the table by applying slight pressure on the top to check for stability.
Step 5 – Level and Inspect
Use a leveling tool to confirm the tabletop is even. Re-tighten any loose fittings and ensure the plastic or rubber caps at the base are intact for floor protection.
4. Lowering Fixed-Height School Tables
If your table has no adjustment mechanism, lowering requires mechanical modification.
Remove the tabletop if it is detachable.
Cut the metal or wooden legs evenly to achieve the desired height.
Smooth and re-cap the leg ends using plastic or rubber feet to maintain stability.
Reattach the tabletop and ensure all screws are firmly tightened.
This process should be performed only by trained maintenance staff or authorized service teams. Aoyasi can customize fixed-height desks upon request for specific classroom requirements.
5. Safety Precautions During Adjustment
Always wear protective gloves when handling metal parts.
Do not lower only one side of the table; uneven height can cause instability and student injuries.
Avoid lowering the table below the manufacturer’s minimum height recommendation.
After adjustment, inspect all joints and fasteners before returning the table to use.
Periodically check the bolts every few months to maintain long-term safety.
6. When to Replace or Upgrade
If the table structure shows corrosion, bent legs, or unstable joints, replacement may be safer than modification.
Aoyasi Furniture Co., Ltd. provides a full range of adjustable classroom desks and tables with reinforced frames and anti-rust coatings. Each model supports easy height adjustment for different student age groups, ensuring comfort, safety, and long-term durability.
7. Conclusion
Lowering a school table is simple when done correctly and safely. For adjustable tables, use the built-in mechanisms to achieve even height. For fixed-height tables, mechanical alteration or professional replacement may be necessary.
