How to Set Up the TITAN Evo’s Lumbar Support, Recline, and Armrests

By VGSources Team 9 min read

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Set up the TITAN Evo in this order: choose your recline angle, adjust the L-ADAPT lumbar height and curvature with the backrest unweighted, then position the 4D armrests. The chair reclines from 85° to 165° when tilt is unlocked. Make one small change at a time while sitting normally, and lock each control before moving to the next.

What each adjustment does

The TITAN Evo has three separate adjustment groups that solve different alignment problems. Recline changes your whole torso position; L-ADAPT changes where and how firmly the backrest supports your lower back; and the 4D armrests position your elbows and forearms.

Adjustment What it changes Important operating detail
Recline Backrest angle for an upright working posture or a more open lounging posture Move your weight off the backrest, operate the recline lever, then return the lever to lock the angle
Lumbar height Vertical position of the lower-back support Turn the height knob counter-clockwise to lower support or clockwise to raise it
Lumbar curvature How far the lumbar support projects into your back Turn the curvature knob counter-clockwise to reduce curvature or clockwise to increase it
Armrest height Vertical elbow position Pull up the height lever, move the pad, and release the lever to lock
Armrest angle and front-back position Pad orientation and how close it sits to your body Hold the front button while changing the angle or front-back position; release to lock
Armrest side-to-side position Width between the two armrests Hold the inner-side button while moving the pad laterally; release to lock

These controls are independent, so a comfortable lumbar setting does not determine the correct armrest setting. Treat each as a separate alignment decision.

Set the recline before anything else

Recline is the first adjustment because changing the backrest angle alters your relationship to the lumbar support and armrests. The TITAN Evo user manual specifies an 85–165° recline range when tilt is unlocked. The angle is measured between the seat and backrest, so a larger number represents a farther-back posture.

How to change the backrest angle

  1. Shift your weight off the backrest. Do not try to release the mechanism while pressing your back into it.
  2. Pull the recline lever fully upward.
  3. Lean back slowly until the backrest reaches the angle you want.
  4. Return the lever slowly to its locked position.
  5. Apply gentle pressure to the backrest and confirm that it stays at the selected angle.

For desk work, begin near an upright position and then open the angle slightly if your shoulders or lower back feel compressed. For reading, watching a video, or another activity that does not require you to reach the desk, a farther-back setting may be more comfortable. The manual gives the available range, not one universally correct angle.

If the backrest will not stay where you put it

  • Take your weight off the backrest and repeat the lever sequence.
  • Make sure the lever has returned fully rather than remaining partway engaged.
  • Do not force the lever or push harder against the backrest while releasing it.

Once the angle is locked, sit in your normal working position. Do not tune the lumbar controls while the backrest is still moving.

Adjust the L-ADAPT lumbar support safely

L-ADAPT uses two independent knobs. One controls height and the other controls curvature. Because they solve different problems, identify the knob before turning it instead of changing both randomly.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Prepare the chair

  1. Leave the backrest at the recline angle you selected.
  2. Remove your weight from the backrest. Secretlab’s TITAN Evo Usage Guide explicitly warns: “Do not put weight on the backrest when adjusting your lumbar support.”
  3. Sit back normally only after the adjustment, so you can judge the result under ordinary use.

Set lumbar height

Use the height knob to move the support up or down your lower back. Turn it counter-clockwise to lower the support. Turn it clockwise to raise the support. Make a small turn, sit normally, and check whether the support is centered in the inward curve of your lower back rather than pressing into your waist or sitting too low on your pelvis.

Set lumbar curvature

Use the separate curvature knob to change how pronounced the support feels. Turn it counter-clockwise to reduce curvature. Turn it clockwise to increase curvature. Increase it only until the support feels present without creating a hard pressure point.

Limits and a reliable tuning method

  • Never turn either knob past its maximum or minimum stop. The Usage Guide says, “Do not turn the knobs past their maximum and minimum points.”
  • Do not turn both knobs at once. Change one variable, return to a normal seated position, and reassess.
  • If the support feels too high, lower the height before changing curvature.
  • If the support is in the right place but feels too prominent, reduce curvature before moving its height.
  • If you cannot feel support where your lower back bends, raise the height in small increments before increasing curvature.

There is no manufacturer-defined setting that fits every body, desk height, or posture. The practical target is stable contact in the lower-back area without forcing your pelvis forward or making you brace against the backrest.

Position the 4D armrests

The TITAN Evo armrests provide four independent movements: height, angle, front-back position, and side-to-side position. Adjust them after recline and lumbar support so your forearms match the posture you will actually use.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Change armrest height

  1. Pull up the height lever on the armrest.
  2. Raise or lower the armrest pad to the desired level.
  3. Release the lever to lock it.

At a desk, start with the pads level with the surface so your elbows can rest without lifting your shoulders. If the pads prevent you from moving close enough to the desk, lower them or use another position that lets the chair approach the work surface.

Change angle and front-back position

  1. Press and hold the button on the front of the armrest.
  2. Move or rotate the pad to change its front-back position and angle.
  3. Release the button to lock the setting.

Bring the pads closer when you need continuous forearm support for keyboard or controller use. Move them away when you need more room to stand, turn, or reach across the desk. Keep the pad orientation aligned with your forearm instead of twisting your wrist to meet it.

Change side-to-side position

  1. Press and hold the button on the inner side of the armrest.
  2. Slide the pad inward or outward.
  3. Release the button to lock it.

Move the pads inward if your elbows drift away from your sides. Move them outward if the chair feels narrow or your elbows are forced against your torso. Recheck the height after a large width change because the new position can alter how your arms meet the desk.

Use a repeatable setup sequence

Randomly changing several controls makes it difficult to tell which movement helped. Use this short sequence whenever you assemble the chair, change desks, or notice discomfort.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.
  1. Choose the activity. Decide whether you are setting up for keyboard work, gaming with a controller, reading, or reclining away from the desk. Your target posture changes with the activity.
  2. Unlock and set recline. Remove weight from the backrest, pull the recline lever fully upward, lean back slowly to the chosen angle, and return the lever to lock.
  3. Set lumbar height. With the backrest unweighted, turn only the height knob in a small increment, then sit normally.
  4. Set lumbar curvature. Turn only the curvature knob in a small increment, sit normally, and decide whether the support is too soft, too prominent, or correctly matched.
  5. Set armrest height. Bring the pads to elbow level without lifting your shoulders.
  6. Set armrest width. Use the inner-side button to move each pad inward or outward until your elbows can remain near your sides.
  7. Set armrest reach and angle. Use the front button to bring the pads toward or away from your body and to align their angle with your forearms.
  8. Verify the locks. Test the backrest and each armrest with gentle movement. A control should remain still after its lever or button is released.

After every change, sit as you normally would for the task rather than leaning deliberately into the mechanism. Small adjustments are easier to evaluate than a full-range movement.

Fix common setup problems

The lumbar support feels too high or too low

Use the height knob, not the curvature knob. Lower it by turning counter-clockwise or raise it by turning clockwise. Remove your weight from the backrest first, and stop at the mechanism’s end points.

The lumbar support feels too aggressive

Use the curvature knob counter-clockwise to reduce the projection. Do not compensate by changing height unless the support is also in the wrong vertical location.

The support is in the right place but does not feel firm enough

Use the curvature knob clockwise in a small increment. Keep the height unchanged while you evaluate the new pressure.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

The recline lever seems difficult to operate

Take your weight off the backrest before pulling the lever fully upward. Lean back gradually, then return the lever to its locked position. Operating the lever while pushing hard into the backrest can prevent a clean adjustment.

  • Compatible with Wide Screens - To ensure compatibility with the dual monitor mount, your each monitor must meet three conditions at the same time: First, computer screens size range: 13 to 32 inches. Second, screen weight range: 4.4 to 19.8 lbs. Third, the back of the monitor screen must have VESA mounting holes with a pitch of 75x75mm or 100x100mm.
  • Regarding the compatibility with desks - Your desk must meet three conditions at the same time: First, desk material: Only wooden desks are recommended, plastic or glass desks cannot be used. Second, desk thickness range: 0.59" - 3.54". Third, the bottom of the desk should not have any cross beams or panels, as this will interfere with installation. We recommend carefully checking that your desk and monitors meets all above conditions before purchasing.
  • Dual C-Clamp Hold - Worried your dual monitors might wobble or slip? Our upgraded base uses a larger platform plus a dual C-clamp structure to lock the dual monitor arm firmly to your desk. Each arm safely keeps your screens steady while you type, click and game—no shaking, no sliding, just a clean and secure setup you can trust every day. It also provides Grommet Mounting installation choice, both options ensure stable and secure fixation for your 0.59" - 3.54" desk.

The monitor stand offers +85°/-50° tilt, ±90° swivel and 360° rotation. Raise your monitor up to 15.75″ to support a healthy sitting posture. Whether you’re working from home, gaming through the night, or switching between video calls and documents, getting the screens to your natural line of sight helps relieve neck, shoulder and back strain so you can stay focused longer with less fatigue.
  • Keep Your Desk Organized: By lifting both screens off the desktop, this dual monitor stand opens up valuable space for your keyboard, notebook, docking station or a simple, clutter-free work area. Built-in cable management guides wires along the arms, keeping cords out of sight and out of the way. Enjoy a tidy, modern workstation that looks as good as it feels to use.

An armrest will not remain in position

Release the relevant button or lever completely after moving the pad. The height lever controls vertical movement, the front button controls angle and front-back movement, and the inner-side button controls side-to-side movement. Test the pad gently after releasing the control.

The armrests look uneven from one side to the other

Some asymmetry can be intentional. Secretlab’s aftercare guidance notes that the right armrest may be installed farther out to accommodate the recline mechanism. Compare the pads’ positions relative to the chair, not the visible positions of the underside mounting plates.

How to correct an installation offset

  1. Remove the adjustment-lever handles.
  2. Using the supplied Allen key, loosen the three M8 screws underneath the affected armrest.
  3. Slide the metal plate inward or outward until the armrest sits correctly relative to the chair.
  4. Retighten all three screws.
  5. Reinstall the adjustment-lever handles and test every movement.

Do not move the plate merely to make the underside hardware mirror the opposite side; use the armrest’s actual position and clearance as the reference.

Working posture versus lounging posture

Use case Recline approach Lumbar approach Armrest approach
Keyboard or mouse work Start near upright and open the angle only as needed Center the support in the lower-back curve; add curvature gradually Keep pads near desk height, close enough for relaxed elbows
Controller gaming Use a more open angle if it lets you see the screen without leaning forward Keep stable lower-back contact while seated farther from the desk Move pads to support forearms without forcing elbows inward
Reading or watching video Use any locked angle within the 85–165° range that keeps your head and torso comfortable Recheck height after reclining because your lower-back contact point changes Move pads back or outward if they interfere with turning or getting up

These are starting strategies, not medical prescriptions. The controls let you match the chair to your body and task; they do not establish one correct posture for every user.

Optional accessories and what you actually need

The TITAN Evo’s built-in recline, L-ADAPT lumbar system, and 4D armrests are sufficient for the three adjustments in this guide. Secretlab lists the Lumbar Pillow Pro, CloudSwap Armrests, casters, and footrests as compatible optional accessories. None is required to set recline, lumbar support, or the supplied armrests.

Consider an accessory only if you have a specific need that the installed parts do not address. An add-on should not be used to bypass the operating limits of the existing knobs, buttons, or recline lever.

Official instructions and video reference

The TITAN Evo Usage Guide supplies the control directions and safety limits used here, including the requirement to remove weight from the backrest during lumbar adjustment and the warning not to turn either lumbar knob past its stop. Secretlab’s official product-usage video, published July 12, 2021, demonstrates recline, 4D armrest movement, and four-way L-ADAPT lumbar adjustment. The user manual’s stated 85–165° range is for an unlocked tilt setting.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Final pre-session check

  • The backrest is at the angle required for the activity and the recline lever is fully locked.
  • The lumbar height and curvature were changed separately with no weight on the backrest.
  • Neither lumbar knob is being forced against its end stop.
  • Armrest height lets your elbows rest without raised shoulders.
  • Armrest width, reach, and angle match your forearms rather than twisting your wrists.
  • Any intentional right-side offset leaves the armrests visually and functionally aligned with the chair.

Product prices and availability are accurate as of the date/time indicated and are subject to change. Any price and availability information displayed on Amazon at the time of purchase will apply.
