We all love to grab the best deals online. But what makes these deals sweeter? The answer is 'Free shipping'! Who doesn't love to have their goodies transported to them at no extra cost? We at Welaxchair are thrilled to provide this facility to all our customers in the lower 48 U.S. states. Doesn't this perk suggest we value not just your money but also your experience?

Free Shipping - For Whom and How Long?

Free shipping is an exclusive offer for customers residing in the 48 contiguous states. Sadly, commodities sent to Hawaii, Alaska, Puerto Rico, Guam, FPO, APO, or PO Boxes are not free due to the higher shipment charges. Orders, once placed, usually take 1-3 days to process and 1-6 business days for delivery.

What about holidays and high-demand periods?

We strive to deliver the best to you even when we're swamped with orders. However, do allowances for delays during national holidays, extreme weather, inventory shortages, shipping carrier delays, custom delays, and other uncontrollable scenarios. Your understanding and patience in these situations is always grate appreciated.

Can I cancel my order?

Yes, you can! If you want to cancel an order, reach out to us at support@welaxhome.com as soon as possible. We can issue a full refund if the product hasn't yet been shipped. However, if the delivery is in progress, cancellation won't be possible.

Need a change of address?

We're swift with our processes. Therefore, post 12 p.m. PST every day, shipping address modifications are not possible. However, our return policy allows you to return an item and have it shipped to a different address.

What about tracking my order?

You'll receive a notification email with your shipment's tracking information once your order leaves our warehouse. You can easily track your package on the official logistics website, either FedEx or UPS. You're always welcome to contact us at support@welaxhome.com with your concerns about shipping.

Welax is fully geared towards ensuring ample customer satisfaction. If, for any reason, you are not completely pleased with your purchase, we have an effective return and refund policy in place. This article will shed light on our comprehensive return and refund policy, what our valued customers can expect, and some crucial policy specifics.

Welax Return Policy - Returning Your Unsatisfactory Purchase

The underlying question may be - "What makes me eligible for a return?" To be eligible for a return, your item should be in the original packaging and saleable condition. This also necessitates having the receipt or proof of purchase. However, it is essential to notify us within 30 days of order receipt.
Nevertheless, for any returns outside of a material defect or an error on Welax's part, customers will be responsible for the freight expenses. These freight charges are non-refundable.

Return Charges - Who Bears The Cost?

With Welax, rest assured that your interests are protected. We will cover your return shipping fees if:

  • Your item has a defect in its materials or workmanship.
  • There are mishaps, such as damage during transit.
  • You receive the wrong product, or it gets lost in transit.
    However, customers need to bear the return shipping fees for subjective reasons, like no longer needing the item or not liking it post receipt. This also applies if the customer provides incorrect information leading to misplaced orders.
Welax Refund Policy - Getting Your Money Back

"What's the process if I'm eligible for a refund?" Once we receive your return parcel, we get down to action right away. If the product is in its original packaging and saleable condition, we initiate a refund promptly. It usually takes 3 business days to examine the returns and another 2-5 business days to process your refund.
Refunds are directly issued back to your bank for payments made with credit or debit cards. However, the actual posting time may vary according to your bank's policy. Please note, for product damages such as scratches, dirt or peel-off paint, we will charge a certain amount as compensation and will keep you notified via email.

Damaged or Missing Shipment

We thoroughly inspect our products before shipping. But do remember to check your product on delivery thoroughly. For any noticed damage or to report missing items during inspection, immediately contact our customer service department within seven days post receipt. Reach out to the Welax team on the Contact Us page within seven days if you notice something missing.

Defective or Errors in Merchandise

In the unfortunate event of receiving a defective item or an incorrect order, please contact us immediately for us to evaluate and rectify the issue.

Disclaimer

Welax reserves the right to deny returns for third-party items or if your return request falls post 30 days from receipt. When in doubt, or for any related questions, please get in touch with us at support@welaxhome.com.

Welax Has Nailed Ergonomic Comfort!

After doing way too much research and trying out a few disappointing chairs, I finally landed on the Welax Ergonomic Office Chair — and I’m honestly thrilled with the decision.

Right out of the box, the chair felt premium. Assembly was quick and easy, with clear instructions and solid parts. Once put together, it was obvious this chair was designed with long-term comfort in mind.

The adjustable lumbar support is the real MVP here. It contours perfectly to my lower back, giving me the kind of support I didn’t even realize I was missing. The mesh backrest is another standout feature — breathable, flexible, and it keeps me from overheating during long workdays.

Comfort Meets Style – The Weax Ergonomic Chair Delivers!

I’ve spent countless hours at my desk working from home, and upgrading to the Weax Ergonomic Chair has been a total game-changer. From the moment I sat in it, I could tell this chair was built with comfort and long-term support in mind.

The lumbar support is incredibly well-designed — it encourages proper posture without feeling rigid or forced. My lower back pain, which used to flare up after a few hours of sitting, has noticeably improved since I made the switch.

The mesh backrest is breathable and keeps me cool throughout the day, especially during longer work sessions. The seat cushion is firm but comfortable, and it doesn’t flatten over time like some cheaper office chairs do.

I also love how adjustable everything is — the armrests, headrest, tilt tension, and seat height all work smoothly, letting me find the perfect ergonomic position. Assembly was straightforward and only took about 20–30 minutes.

On top of all that, it just looks great. Sleek, modern, and professional. It adds a polished touch to my workspace.

If you’re looking for an ergonomic chair that balances comfort, quality, and value, I highly recommend the Weax. It’s a smart investment for anyone who spends serious time at a desk.

A really wonderful chair!!!!

This chair revolutionized my WFH experience! The lumbar support auto-adjusts perfectly - zero back pain even after 8 hours. 6D armrests are a game-changer for typing posture. Worth every penny for spine health.

After comparing multiple brands, I chose this model, which is fully functional: it has a headrest, lumbar support, and a sliding seat cushion. The installation took 20 minutes, but the instruction manual was clear. The only minor drawback is that adjusting the headrest requires a lot of effort.
