We ship all orders within 5–7 business days via UPS Ground. Please note that this processing time does not include UPS transit time, which varies by location.

For local pick-up, we are available by appointment only and do not offer same-day pick-up. Scheduling an appointment allows us to confirm availability of your preferred chair and options, and ensures your chair is fully prepared before your arrival.

If you would like to arrange a pick-up or have any questions, please contact us at support@nulifechairs.com

Every Nulife Chair purchased after 2022 comes with two layers of protection – a 30-day full warranty and a lifetime warranty for mechanical issues.

30-Day Full Warranty

For the first 30 days after delivery, your chair is covered for any issue, including mechanical parts, mesh, frame, or cosmetic concerns.
If something isn’t right, we’ll repair, replace, or refund your chair to make sure you’re completely satisfied.

Lifetime Warranty (Mechanical Issues)

After the first 30 days, your chair remains protected under our Lifetime Warranty, which covers all mechanical components, including:

  • Tilt and recline mechanisms
  • Gas lift cylinder
  • Arm adjustments

If a covered part fails under normal use, we’ll repair or replace it free of charge, with free shipping for replacement parts anywhere in the U.S.

For customers within our serviceable area near Los Angeles – including Palmdale, Pasadena, Burbank, Glendale, Santa Monica, Culver City, and West LA – we may also offer on-site repair assistance.

Outside these areas, you can complete most repairs with simple self-installation, and we’ll guide you through every step with clear instructions and support.

Warranty Conditions

  • Applies to normal use (up to 40 hours per week, 250 lb weight limit).
  • Valid for the original purchaser only (non-transferable).
  • Proof of purchase may be required.

What’s Not Covered

  • Normal wear and tear (scratches, scuffs, fading).
  • Improper assembly, misuse, or modifications.
  • Negligence or customer-supplied parts.
  • Mesh or frame issues beyond the limited coverage period.
  • Cosmetic or aesthetic damage after delivery.

Note: The warranty does not cover damage caused by shipping carriers, movers, or repair technicians not arranged by Nulife Chairs. If you booked your own carrier or mover, please contact them directly for delivery-related claims.

How to File a Claim

To file a claim, email support@staging.nulifechairs.com with your:

  1. Order number
  2. Photos or short video showing the issue
  3. Brief description of the problem

We’ll review your claim quickly and send the appropriate replacement or repair solution at no cost.

Important Notes

  • The lifetime warranty applies only to mechanical issues.
  • If a part is discontinued, we’ll provide an equivalent new or reconditioned part.

For full details, visit our Lifetime Warranty Information page or contact support@staging.nulifechairs.com anytime – we’re always here to help keep your chair in top shape.

The chair can be easily assembled by aligning the backrest with the seat frame and securing it using the four screws included in the package.

This Herman Miller Aeron, Size B, has passed our 20-point refurbishment inspection — cleaned, mechanically tested, and verified part by part — then backed by a lifetime warranty on mechanical components. Customers rate it 4.75/5 across 68 reviews, and it’s yours for 60% less than brand new.

What “Refurbished” Means at Nulife Chairs

Every chair we sell goes through the same process before it reaches you:

  • 20-point inspection covering tilt mechanism, gas cylinder, arm adjusters, casters, and frame integrity
  • Deep clean of mesh, frame, and base
  • Function testing on every moving part — tilt lock, recline tension, lumbar adjustment, arm height/pivot
  • Cosmetic check — light wear (small scuffs or scratches on the base or frame) may be present on individual units, but nothing that affects performance. We’ll always disclose anything beyond normal light wear.

This is what separates a Nulife refurb from a random resale listing: you’re getting a chair that’s been tested to perform like new, not just wiped down and re-photographed.

Built for Medium-Sized Users

Size B is Herman Miller’s most popular size, designed to comfortably fit users roughly 5’4″ to 6’2″. The breathable mesh seat and back stay cool during long sessions, and the fully adjustable arms, tilt, recline, and lumbar support let you dial in your exact posture — something reviewers consistently point to, from reduced back pain to full-day comfort during long coding or Zoom sessions.

What Customers Say

  • Corporate and small-office buyers have purchased multiple units at once, citing consistent quality across the batch
  • Multiple reviewers note the chair “doesn’t feel refurbished at all” — tight mesh, no squeaks, smooth recline
  • The adjustable lumbar and arm supports are the most frequently cited feature for reducing back and shoulder strain during long workdays

    Looks almost new

    USFremont, CA

    Chair looks nearly new and performs like a brand-new unit. The mesh and adjustments feel tight, and everything functions smoothly. The shipping box showed some wear from transit, but the chair itself had no damage at all. Overall, a very positive experience for a refurbished purchase.

    Learning curve but worth it
