While alignment with your knees feels stable, it is not the ideal ergonomic height for your desk and is likely the direct cause of your wrist soreness.
Setting a desk too low forces you to lean on your wrists to reach the keyboard, which compresses the carpal tunnel and sensitive nerves in the inner wrist.

The Ideal Height: The “90-Degree Rule”
Rather than using your knees as a guide, use your elbows
.
To find your ideal height:
Adjust your seat first: Sit with your feet flat on the floor and knees bent at approximately 90 degrees.
Find your elbow height:
Relax your shoulders and bend your elbows to a 90-to-110-degree angle. Your forearms should be parallel to the floor.
Set the desk height: The top of your keyboard should sit at or slightly below this elbow height.

Why Raising the Desk Corrects Wrist Soreness
Raising your desk to elbow level will likely alleviate your pain because:
Neutral Positioning: It allows your wrists to stay in a “neutral” straight line rather than bending them upward or downward to reach the keys.
Pressure Relief: When the desk is at the correct height, your arms are supported by your shoulders and core. At your current “knee-height” setup, you are likely using the desk as a weight-bearing surface for your upper body, pressing your inner wrists into the hard edge.
Shoulder Relaxation: A higher surface prevents you from hunching forward, which often leads to shifting your weight onto your hands.

Quick Fixes for Your Setup
Add More Layers: Since you are using cardboard, continue stacking until the surface meets your relaxed elbow height.
Monitor Riser: Once you raise the desk, your laptop screen will likely be too low, which can cause neck strain. Use a separate box or riser to bring the top third of the screen to eye level.
Edge Padding: Because you are using cardboard sheets, the edges can be sharp. Consider duct-taping a rolled-up towel or foam to the edge of your “desk” to act as a soft wrist/palm rest.
