8 Points of Ergonomic Adjustment

At Porvata, we strive to educate our customers to allow them to get the most out of our, or our competitor's products. Whether you are tweaking your chair to sit at an automatic adjustable desk or a new office desktop, see our 8 Points of Ergonomic Adjustment video below and never look at a chair the same again!

Height Adjustment:

Using the lever on the right side of your chair, adjust your seat cushion to the correct height. Your should maintain an arm angle between 70 degrees and 135 degrees for optimal posture and support throughout the day.

Tilt Lock:

Pull the left knob out and twist forward to unlock tilt lock functionality. Choose between 5 different locking positions - from upright to lounge mode - and work the way you want!

Seat Slider:

Slide your seat forward or backward using the lever on the left side of your chair. The seat is properly positioned when you can fit between two and four fingers between the back of your knee and the seat cushion. This helps maximize blood flow throughout the day while enabling the seat and lumbar support's functionality.

Tilt Tension:

Pull on the knob on the right side of your seat cushion. Twist the knob forward to increase tilt tension, making it harder for you to lean back in your chair, and backward to release tension.

Armrest Height:

Use the tab on the outside of each armrest to adjust height.

Armrest Pivot:

Twist armrest inward to provide support for your forearms while typing.

Armrest Position:

Slide armrests forward or backward to maximize comfort.

Lumbar Support:

Slide the lumbar support bar up or down to fit your posture.

Shipping Information


Please allow 1-4 business days for order processing. Transit time is normally an additional 3-5 business days.


Porvata ships all desks under 60", chairs, and accessories via FedEx Ground.

Orders for desks greater than 60", pedestals, credenzas, and multi-desk orders must be palletized and shipped via FedEx LTL (Less-than-truckload).


Currently, Porvata ships to the contiguous United States (all states except for Alaska and Hawaii). At this time, we do not ship internationally.


Porvata ships all desks under 60", chairs, and accessories via FedEx Ground.

For desks greater than 60", pedestals, credenzas, and multi-desk orders, there are two types of delivery options: curbside delivery or inside delivery. The majority of our deliveries are curbside deliveries. The FedEx driver will deliver the pallet outside of your house and depart from there. You are then responsible for bringing the item inside.

If you would like us to arrange inside delivery, we are able to arrange this for you at the time of purchase. We will pass through the cost (which is typically significantly higher than a standard delivery fee) and upgrade the delivery. With inside delivery the driver(s) will carry the item inside your home. Additional or extraordinary delivery requirements (multi-level buildings, etc.) may incur additional delivery charges.


While we do our best to ensure your items arrive safely, we cannot guarantee it. Therefore we ask all of our customers to carefully inspect items for damage before signing for it. Inspect the box for obvious damage first, and if able, try and inspect the inside for any concealed damage. We will replace damage items, but it is much easier for us to file a claim with FedEx if you refuse the shipment.

Call FedEx immediately or reach out to us.


When we ship your order via FedEx's freight service, you will receive an email from us with tracking, as well as an email from FedEx. Prior to delivery, a member from FedEx's team typically will reach out to you to schedule a delivery window.
