RELAXONCHAIR YUKON-4D Massage Chair Review

The YUKON-4D is the most expensive massage chair from RELAXONCHAIR, a Fullerton, California company that sells its own chairs direct; its product page says the chair is designed in the USA and made in China. The user manual linked from the product page dates from 2021, so this is an established model rather than a new release. The store lists it at $6,499 next to a crossed-out $10,499; this review quotes what you would pay.

Its main feature is a 4D roller mechanism: the rollers travel along your back and also push in and out, with four depth settings on the remote. It uses six techniques — kneading, tapping, the two combined, shiatsu, knocking and rolling — and begins by scanning your body from the seat to the shoulders. The product page calls the track a newly designed J-Track; the 2021 manual describes an S-and-L-shaped track that runs under the seat to the glutes.

The chair has 76 airbags, in the shoulders, arms, back, waist, hips, thighs, calves and feet, with five intensity levels. Heat comes from the back rollers, which the store describes as light warmth, and from the foot section, which uses triple foot rollers with heel pressure points. The store's FAQ warns that its chairs' foot rollers can feel intense and suggests socks or a towel, or turning the foot rollers off.

You get 12 automatic programs — six regular ones and six more under a Special menu — plus an 8-minute quick session and a manual mode where you choose the technique, the area, the width, the speed and the 4D depth. Sessions last 10, 20 or 30 minutes, and the manual caps one session at 30. Voice control responds to seven set phrases, such as starting zero gravity or shutting the chair down, after a wake phrase, and built-in Bluetooth speakers play music from a phone.

Three zero-gravity positions tilt the chair back with your legs raised, and the footrest extends up to 8 inches on its own. The space-saver design needs just 2 inches behind the chair, per the spec table. It measures 65 inches long, 34 wide and 51 high upright, and 79 inches long reclined. RELAXONCHAIR recommends it for users from 4'11" to 6'6"; its spec table gives a 300 lb limit, while the feature list says it is rated for 320 lb, so plan around 300.

Delivery is free by freight to the curb in the continental US, in 5–7 business days, with a 2–4 hour appointment window and a signature; Alaska and Hawaii cost extra, and P.O. boxes, military addresses and US territories aren't served. The chair weighs 344 lb and ships in three boxes totaling 409 lb, and you attach the armrests and the footrest. White Glove delivery, which carries it to the room you choose, unpacks and sets it up and takes the packaging away, costs $500 more.

The 3-year limited warranty covers parts and labor in the first year, including an on-site visit where one is available or transport to a repair center. In the second year it covers parts only, and you pay for labor or shipping; in the third, only the main frame. It covers the original buyer and home use only, and damage in transit is claimed with the carrier. You can request a return within 30 days of delivery if the chair is unused and in its original packaging, minus a 15% restocking fee, and you pay the return shipping. The same policy says sale items can't be returned, so ask how that applies to this chair before you buy.

The manual lists people who should not use the chair, or only with a doctor's advice — among them people with osteoporosis, spine or disc problems, heart disease or a pacemaker, pregnant women and people over 80. The store's product page shows three customer reviews: two five-star, and one one-star from December 2021 about a Christmas delivery that hadn't arrived, so order early if it's a gift. Within the range, the MK-V Plus ($2,499) lists an L-track, 38 airbags and lower-back heat, and the Jasper ($1,599) arrives fully assembled.

Specifications

How it compares

On Oct 25, 2026 the YUKON-4D was $6,499, the MK-V Plus $2,499 ($4,000 less) and the Jasper $1,599 ($900 below the MK-V Plus). The YUKON-4D page lists 76 airbags against 38 and 18, a 4D roller mechanism against the MK-V Plus's six-roller 50-inch L-track and the Jasper's four-roller 57-inch SL track, heat in the back rollers and the feet against lower-lumbar heat on the other two, and voice commands and Bluetooth speakers (the Jasper lists Bluetooth speakers and a USB port; the MK-V Plus feature list names neither). It is also the heaviest: 344 lbs against 234 lbs and 185 lbs, shipped in three boxes (409 lbs) with armrests and footrest to attach, against one box for each of the others, and White Glove costs $500 against $400. Its page says genuine leather, the MK-V Plus description says synthetic leather, and the Jasper page names no material.

Who it suits: the YUKON-4D for a tall user (the page says 4'11" to 6'6") who wants the most airbags and heat in the rollers and feet, and can take a 409 lb three-box freight delivery; the MK-V Plus for a mid-priced L-track chair for users up to 6'5"; the Jasper for a smaller user (5'2" to 6'2", up to 264.5 lbs) who wants a chair that arrives fully assembled at $1,599. All three pages show a crossed-out price, so the refund policy's ban on returning sale items looks to cover each.

Shipping, returns and warranty

Read on Oct 25, 2026 from the store's shipping policy, refund policy, warranty page and terms of service, with its contact and home pages checked for conflicts. Where they say nothing, the point says so.

• Where it ships: the continental United States for the free standard service. Orders deliverable to Hawaii and Alaska "include a standard shipping fee"; the policy points to 1-866-647-3496 or [email protected] for them. It cannot deliver to P.O. Box addresses, military stations or other U.S. territories.
• Shipping fee: "Free standard shipping for all U.S. continental"; the Hawaii and Alaska fee is not stated. White Glove service, which carries the item inside, costs "an extra charge" and its price is not stated.
• Timing and delivery: the free service is delivered by freight in "5-7 business days". It arrives "at your curbside only" and needs a signature; carrying it inside is what the paid White Glove service adds. A shipping agent contacts you after purchase to set an appointment, and the policy asks you to allow a 2-4 hour window.
• White Glove service: for an extra charge a team moves the item to a room of your choice, unpacks and sets it up, and removes the debris. The policy warns to check the pathway width first, because some units are pre-assembled and the delivery agent "will not disassemble" the item to fit it through. A signature is required. The shipment leaves "our CA warehouse" for a local nationwide trucking company, whose delivery agent calls you to set the date and time once it reaches their local warehouse.

• Return window and condition: 30 days after receiving the item to request a return. The item must be in the condition you received it, "unworn or unused, with tags, and in its original packaging", with the receipt or proof of purchase.
• Return shipping and fees: "You are responsible for your return shipping charge." If you cannot find a carrier, the store "may provide return shipping arrangement", with the cost deducted from the refund. A 15% restocking fee is also deducted from the refund. The page does not say how a large freight item is to be sent back or what that would cost, and it gives no return address.
• How a return starts: email [email protected]; the page gives no other steps.
• Refunds: after the store receives and inspects the return, it says whether the refund is approved. If approved, the refund goes to the original payment method "within 10 business days", plus your bank's processing time. If more than 15 business days pass after approval, the page says to contact the store.
• Damaged or wrong items: inspect the order on reception and contact the store "immediately" if an item is defective, damaged or the wrong one.
• Not returnable: perishable goods, custom products, personal care goods, hazardous materials, flammable liquids or gases, sale items and gift cards. For an exchange it says to return the item and, once the return is accepted, buy the new one separately.

• Warranty length: a "Limited Three (3) Year Warranty" for the original purchaser against manufacturing defects in workmanship and material, from the original date of purchase, with proof of purchase required. It is not transferable to a second-hand owner.
• What each year covers: year 1, parts and labor, including transportation to and from an authorized repair center when on-site repair is not available (a technician can repair in-house at no cost where one is available). Year 2, defective parts or components only; you pay labor (standard service rate plus mileage fees) and transportation to a repair center. Year 3, the main structural body frame only, replaced if it bends or breaks; other parts and labor are available "at an additional cost". A replacement part is covered for 1 year from the date of receipt.
• Warranty exclusions: normal wear and tear (Velcro, zippers, fabric tears, cosmetic covers and the items on its parts and accessories page); misuse or abuse; a unit not assembled or installed per the instructions; damage in shipping, where claims go to the carrier; stains, fluids, mold, water, animal damage, cuts and burns; acts of God; other property damage or economic loss; second-hand owners; commercial use, which "voids this warranty"; products bought from unauthorized sellers; unnecessary service calls (you may be charged standard rates if no issue is found); "installation, set-up, or relocation from the originally installed location"; and modifications, improper power use, electrical disturbances and surges.
• Warranty claims: email [email protected] or call 1-866-647-3496 with proof of purchase. A Repair Order Number is assigned once the store receives the claim, and an authorized repair center "will not accept any repair without" it.
• Prices and errors: the terms let the store change prices without notice and correct errors in descriptions, prices or shipping charges, including by canceling an order after it has been placed.
• Seller and contact: the terms say the site is operated by RELAXONCHAIR, but their contact block shows unfilled template fields for trading name, business address, phone, registration number and VAT number, so no page names a legal entity or street address. The pages give [email protected] and 1-866-647-3496, and the contact page is a message form only. The terms are governed by United States law.

Where the pages disagree

• Free shipping: the home page says "All of our products come with FREE Curbside Delivery", while the shipping policy limits free standard shipping to the continental U.S. and says Hawaii and Alaska orders include a fee.
• Warranty: the home page says "3 year warranty to ensure your complete satisfaction". The warranty page gives full parts and labor only in year 1, parts only in year 2 with labor and transport at your cost, and the frame only in year 3.
• Where it ships: the shipping policy delivers to the continental U.S., plus Hawaii and Alaska for a fee, but the refund policy carries a "European Union 14 day cooling off period" clause for merchandise "being shipped into the European Union".
• Sale items: the refund policy says it "cannot accept returns on sale items" and does not define them, while the home page shows percentage-off badges (38% to 47%) on all of its listed best sellers.
• Damage in transit: the refund page says to contact the store "immediately" about a damaged item, while the warranty page excludes damage in shipping and says such claims "must be addressed and resolved with the designated carrier".

For this product, delivery is free curbside freight in the continental US (no order threshold; Hawaii and Alaska carry a fee), 5-7 business days with a signature, White Glove +$500; the page shows $10,499 crossed out ("-39%"), which makes it a sale item the refund policy says it cannot take back, and any other return carries a 15% restocking fee plus your return freight; the page shows it in stock, with a banner saying only 8 are left.
