AndaSeat Kaiser 4 vs Kaiser 3: What Changed and Which to Buy

Research note: This comparison uses AndaSeat's published spec sheets, feature pages and US store listings, not a hands-on Chairpedia test. Figures are quoted as the brand states them, with the size they apply to.

Introduction

The Kaiser 4 is AndaSeat's current flagship and the Kaiser 3 is the generation it replaced, and AndaSeat still sells both. In one sentence: the Kaiser 4 adds 6D armrests, a 24° pop-out lumbar with an any-angle lock and a five-year warranty stated on its product page, while the Kaiser 3 keeps a deeper 155° recline, a lower list price and AndaSeat's standard 3-year limited warranty. Both come in L and XL sizes with the same stated weight limits, so the choice is about controls, recline and price rather than who fits.

At a glance

AndaSeat Kaiser 4 — strengths and weaknesses

Documented features: AndaSeat's Kaiser 4 spec sheet lists 6D armrests (up-down, right-left, forward-backward, upward tilt, armpad rotation and arm rotation) with 2.76 in (7 cm) of height adjustment, a 24° pop-out lumbar with an any-angle lock and built-in in-out and up-down adjustment, a magnetic head pillow and a 90°–135° backrest recline with 15° rocking. The seat sits 18.11–20.67 in (46–52.5 cm) off the floor in both sizes. The L size has an 18.50 in (47 cm) seat depth, a 19.29 in (49 cm) seat width including the side bolsters and a 32.28 in (82 cm) backrest; the XL size goes to 20.08 in (51 cm), 21.26 in (54 cm) and 34.05 in (86.5 cm). AndaSeat rates the L at 260 lb and the XL at 395 lb, and the Kaiser 4 product page states a five-year warranty.

Check before buying: The recline stops at 135°, twenty degrees short of the Kaiser 3, so if you nap in your chair the older model reclines further. It is a heavy chair: AndaSeat lists a net weight of 71.87 lb (32.6 kg) for the L and 73.55 lb (33.36 kg) for the XL. The L size is recommended for 150–180 cm (4 ft 11 in to 5 ft 11 in) and under 120 kg (260 lb); the XL for 181–210 cm (5 ft 11 in to 6 ft 11 in) and 80–180 kg (175–395 lb). The AndaSeat US store lists the Kaiser 4 at $549 (L) to $579 (XL) in PVC leather or linen fabric.

AndaSeat Kaiser 3 — strengths and weaknesses

Documented features: AndaSeat's Kaiser 3 feature page lists 4D armrests with 5.1 in of up-down travel, 1.18 in of right-left and forward-backward movement and 70° of inward-outward rotation, an integrated 4-way lumbar that moves 3.0 in up-down and 1.18 in in-out, a magnetic head pillow with a 7.9 in attachment range, and a 155° backrest recline with a 15° rocking mode. Seat height for the series is listed as 17.52–20.08 in (44.5–51.0 cm). The L size is recommended for 4 ft 11 in to 6 ft 2 in and under 260 lb; the XL for 5 ft 11 in to 6 ft 11 in and 175–395 lb.

Check before buying: The Kaiser 3 pages we checked do not publish seat depth, seat width or backrest length, so compare its size guide with the Kaiser 4's measured figures rather than assuming the two generations share a seat. Its standard cover is AndaSeat's 3-year limited warranty, which the brand says can be extended to five years free of charge after registration. The AndaSeat US store lists the Kaiser 3 at $499 (L) to $519 (XL) as its compare-at price; the store's sale price was lower when we checked, and the FlyQuest edition is priced separately.

How they differ

Armrests: The Kaiser 4's 6D arms add an upward tilt, armpad rotation and whole-arm rotation to the four movements the Kaiser 3's 4D arms already have. AndaSeat quotes the two differently — 5.1 in of up-down travel for the Kaiser 3 on its feature page, 2.76 in (7 cm) of height adjustability for the Kaiser 4 on its spec sheet — so treat those as separate measurements, not a cut.

Lumbar: The Kaiser 4 replaces the integrated 4-way lumbar (3.0 in up-down, 1.18 in in-out on the Kaiser 3) with a pop-out lumbar that swings out up to 24° and locks at any angle, while keeping in-out and up-down adjustment.

Recline: This is the one spec where the older chair goes further: the Kaiser 3 reclines to 155° against the Kaiser 4's 135°. Both add 15° of rocking.

Seat height: The Kaiser 4 sits slightly higher at 18.11–20.67 in (46–52.5 cm) versus 17.52–20.08 in (44.5–51.0 cm) for the Kaiser 3. Shorter sitters should check that the lowest Kaiser 4 setting still lets their feet rest flat.

Size guide: Both come in L and XL with the same 260 lb and 395 lb limits, but AndaSeat narrows the Kaiser 4's L height range to 150–180 cm (4 ft 11 in to 5 ft 11 in), where the Kaiser 3's L covers 4 ft 11 in to 6 ft 2 in. A sitter around six feet tall lands in L for the Kaiser 3 and in XL for the Kaiser 4.

Warranty and price: The Kaiser 4 product page states a five-year warranty; the Kaiser 3 carries the standard 3-year limited warranty with a free extension to five years on registration. On list price the Kaiser 4 runs $549–$579 against $499–$519 for the Kaiser 3, before store sales.

Who should buy which

Consider the AndaSeat Kaiser 4 if:

• You want arms that tilt and rotate (6D) rather than the Kaiser 3's 4D set

• You want a lumbar that can be locked at a chosen angle instead of a fixed integrated pad

• You are between 150 and 180 cm and under 120 kg (L) or 181–210 cm (XL), per AndaSeat's size guide

• A five-year warranty stated on the product page matters to you

Consider the AndaSeat Kaiser 3 if:

• You recline a long way: 155° against 135°

• You want the lower list price, or the store sale price on the outgoing model

• You are around six feet tall and want to stay in the L size

• You do not need the pop-out lumbar or the extra arm movements

Bottom line

Neither generation is a universal pick. The Kaiser 4 is the more adjustable chair on arms and lumbar and carries the longer stated warranty; the Kaiser 3 reclines further and lists lower. Match the size guide to your height first, then decide whether the extra adjustments are worth the difference in price.
