Dowinx puts a heated lumbar massage on its Heated Massage Series MB38, a reclining gaming chair sold at DOWINX’s own store.
This verdict is built from the published spec sheet, the brand’s own policy pages and the review summary on its product page, not from sitting in the chair. It covers what the chair includes, how it fits, what reviewers report, how it compares with Furmax and what the return rules look like.
The short version: a well-equipped pick for anyone who wants heat on the lower back, as long as you accept that the massage lives in a pillow and not in the seat.
What You Get With the MB38
The MB38 is a reclining gaming chair built around a pocket spring cushion. Instead of one block of foam, the seat uses coils wrapped one by one, and the brand’s stated aim is to relieve pressure points over long sittings.
Dowinx is run by Hongkong Minai Trading Limited, based in Wan Chai, Hong Kong. The company says the whole process, from planning and materials to design and manufacturing, stays inside its own operation, and its product pages name the frame hardware in detail.
The brand’s listing gives these specs:
- Price: check the current price at DOWINX
- Upholstery: fabric on the green version shown here, with PU leather on other colorways
- Recline: the backrest tilts from 90 to 135 degrees
- Lift: a gas cylinder with a TÜV Class-4 rating
- Mechanism: an aluminum tilt mechanism
- Base: heavy-duty nylon with quiet swivel casters
- Armrests: 360-degree adjustable linkage armrests
- Extras: a heated massage lumbar pillow, a 3D ergonomic neck pillow and a stowable footrest
How the heat and massage work
The MB38 does not hide a motor in the frame. Its dual-direction lumbar massage and heat come from a removable memory foam pillow studded with acupressure nodes, and a separate control runs them.
In practice the effect stays at the lower back and does not reach the rest of the seat. Treat the pillow like any small electronic device: keep liquids off it and do not crease it. I would see the massage as a comfort feature and nothing more.
To see colors and the current listing, browse DOWINX’s range at its own store, where the Heated Massage Series is sold.
Size and Fit
The seat measures 21.26 inches wide and 20.48 inches deep, with 3.94 inches of cushion thickness. Seat height runs from a low of 18.3 inches to a high of 21.46 inches.
The backrest stands 32.28 inches tall and 22.4 inches across. Hold those numbers up against your own desk and frame before you order.
Dowinx’s sizing guidance names height as the biggest factor, putting it at roughly 26 percent of overall fit. Standard chairs from the brand are generally rated for 290 to 300 pounds, so anyone above that range should look at the Big and Tall listings instead.
The Wide Office Series (66D3) offers a broader seat without moving fully into Big and Tall. The QL-66B3 in the Big and Tall line is listed up to 400 pounds, in black or grey.
What Reviewers Report
The MB38 page on the brand’s own store shows about 240 reviews, with roughly nine in ten giving five stars. That is a sizable sample, though it is the brand’s own review page, so read it with that in mind.
Reviews on the brand’s product page return to three themes: owners use the heat and massage function daily, shipping is quick and the value feels fair for what comes in the box.
The complaints on that page are specific. One recurring complaint is that the armrests rotate but do not raise or lower, and a smaller group would rather have the massage motor inside the seat than in a separate pillow.
Neither point is a dealbreaker. Both are worth knowing before you buy a chair you cannot easily try first.
Owner comments on a brand’s own page are useful for spotting patterns, but they are not an independent audit, so weigh them alongside the specs.
How It Compares With Furmax
Furmax is a budget brand that offers a lumbar massage feature too, which makes it a fair yardstick. Its massage models typically list for roughly $120 to $160, and on sticker price Furmax is usually the cheaper option next to the MB38.
The real gap is heat. Furmax uses a USB-powered lumbar support with vibration only, while the MB38 adds heat to the vibration. If warmth on your lower back is the point, that decides it. If vibration is enough, Furmax is the thriftier route.
Recline range is the other difference on paper. Furmax lists 90 to 165 degrees, against 90 to 135 on the MB38. Weight ratings are close, with both brands quoting about 290 to 300 pounds for standard chairs.
Dowinx also documents its build more specifically, naming the gas lift rating, the aluminum tilt mechanism and the spring cushion. Furmax listings lean on a steel tube base with less spring detail, and they carry less documented manufacturing history than the roughly 15 years Dowinx says it has behind it.
Who It Suits and Who Should Skip
The MB38 suits people who sit for long stretches and want heat and vibration at the lower back from a reclining chair with a pocket spring seat.
Skip it if you need height-adjustable armrests, since owners report that these only rotate. Skip it too if you want the massage built into the seat, or if you are above the standard weight rating.
If you prefer a quieter, more office-like look, Dowinx sells an Executive Office Series in white or black, in fabric or PU leather, without the massage feature.
A lighter, more playful option is the Cute Series, with a cat-ear headrest and two-tone colorways.
Shipping, Returns and Warranty
Per the brand’s help pages, an order spends up to one business day in processing and then travels with FedEx for three to seven business days. It leaves from whichever of the brand’s warehouses (Germany, the US, the UK, China or Japan) can reach you soonest. Shipping is free on orders above $99 within the US, Japan and EU countries.
Plan on building the chair yourself. Dowinx calls assembly not complicated and posts a video and a written guide under Technical Support, and in some regions the brand also sells an assembly service. Before the first sit, make sure every bolt is fully tight.
On returns, the brand separates fault from preference. It pays the postage when it shipped the wrong item or the chair arrived damaged or defective. If you simply change your mind, the cost of sending it back is yours.
A refund request has to come within 30 days of delivery. The chair must be new, unused and not installed, packed in its original box with the manuals, the blank warranty card and all accessories. That condition leaves little room to try the chair first.
Coverage runs two years from delivery on every chair. Dowinx also points to an optional Worry-Free Purchase plan through Seel, and its own estimate is a life of more than three years under normal use.
FAQ
Does the MB38 have a motor inside the seat?
No. The massage comes from a lumbar pillow, not from the seat or frame, and its heat and vibration run from a separate control.
How far does it recline?
The backrest tilts from 90 to 135 degrees, and a stowable footrest comes with it.
What weight does it support?
Standard Dowinx chairs are generally rated between 290 and 300 pounds. Check the rating on the MB38 page before you order, and look at the Big and Tall line if you need more.
How do I clean it?
Keep drinks away and wipe the chair down on a regular schedule. PU leather is the easy case, since a damp cloth with a little mild soap is enough. Fabric needs more patience: dab a spill up right away instead of rubbing it in, and vacuum from time to time.
Who do I contact about an order problem?
For any order problem, write to [email protected] and quote the order number. If the order needs a different color or model, send the brand a note through its Contact Form quickly, since a shipped order cannot be canceled.
The Verdict
On paper, the MB38 combines a pocket spring seat, a 90 to 135 degree recline, a TÜV Class-4 gas lift and a heated massage pillow in one chair, and the brand documents each part by name.
The trade-offs are clear and easy to check: rotating-only armrests, a massage pillow rather than a built-in motor and a return policy that expects an unused chair. Compare the size numbers with your own frame before ordering.
If heat on the lower back is what you are shopping for, the MB38 is the chair to check, and you can browse DOWINX’s range at its own store to find it. Confirm the current price at DOWINX before you order.
