Things to Consider When Buying an Under-Desk Treadmill

Here’re the things you should look for when buying a 300 lb or higher capacity under-desk treadmill for home or office use.

Weight Capacity

The first and obvious thing you should check out is the weight capacity of the treadmill, especially when if you’re a heavy user.

As we mentioned earlier, you should look for a 30-50 higher weight capacity treadmill than its most massive user.

For example, if your body weight is 250 pounds, then a 300 pounds capacity treadmill can serve you very well. But if you’re a 290 pounds person, it’s better to go for a higher capacity treadmill (i.e., 350 lb).

This thumb rule will help you increase your treadmill’s stability and durability in the long run.

Low Noise

A quiet treadmill motor is always recommended, especially when you’re going to use it during work, because keeping the workplace silent is very important.

Look for an under-desk treadmill with good noise cancellation technology.

Motor Power

Motor horsepower is one of the crucial factors to check out when it comes to getting a smooth running experience.

A 250 lb person may find a 2.0 HP motor is sufficient for walking, while a 350 person may need a more powerful one.

A 4.0 mph speed is enough for an under-desk walking treadmill.

Remember, the more powerful the motor, the better.

Deck Size

When you’re buying an under-desk treadmill for heavy people, it is mainly for walking purposes. And for walking, a 16″ x 40″ deck is sufficient for most people.

However, if you’re a tall user or have a wider walking style, look for a more spacious deck (i.e., 20″ x 50″). You’ll find it in our top pick list.

Warranty Coverage

Warranty is always proof of security. If you find any fault in your equipment in the future, it will help you get the service from the manufacturer without spending a single penny.

Many affordable under-desk treadmills provide about 1-3 years or a maximum ten years frame warranty. You may find a lifetime warranty in some higher-end under-desk treadmills.

Again, the more, the better.

Final Word

When you’re buying an under-desk office treadmill, look for a quiet motor, an optimal size deck, and a slightly higher weight capacity than your body weight.

Check out our top pick list above to find your perfect match.

So… There we have it: The best under-desk treadmill with 300 lb capacity.
