Review: Thuma Classic Bed Frame

Many consider solid-wood furniture to be a big-ticket item, and for good reason. When crafted expertly, its sturdiness and lifespan are pretty unparalleled—especially in an era of short-lived, cheap furniture from Amazon. I’m all for operating within your budget, but I’m also someone who believes that solid-wood furniture and its craftsmanship can’t be beat. Maybe it’s because I grew up near an area that used to be a landmark epicenter of furniture production, High Point, North Carolina. Or, perhaps it’s because, as a veteran mattress tester, I can tell you that your mattress will only perform as well as the frame it is set upon.

To set sleepers up for success, I researched the best bed frames on the market. One platform bed frame in particular was highly recommended by multiple members of the WIRED Reviews team: the Thuma Classic Bed frame, or “The Bed” for short. Thuma’s ethos revolves around sustainability, easy assembly, and quality. I had to see for myself how the Classic Bed frame upheld these standards.

I’ve covered Japanese joinery bed frames before in my guide to the best Thuma dupes (for those of us balling on a budget). For the most part, furniture and buildings made with this ancient technique are meant to be put together without tools or screws. It’s not just for simplicity’s sake, as it's intended for stability. The Japanese joinery technique was developed to support Japanese architecture and keep it structurally intact during earthquakes. On a much smaller scale, this technique helps the Thuma bed frame from shaking too much and focus all its efforts on supporting the mattress—and, subsequently, you on top of it. How the technique is put into practice can be boiled down to the interconnectivity of all the parts involved. Each piece of the frame slides into the surrounding pieces, creating a framework that relies on each part for overall support.

The frame uses repurposed rubberwood sourced from the same rubber trees used to produce latex for Thuma’s hybrid mattress line (read our review of the Medium firmness model here). This practice of Thuma’s single-sourcing its materials—both upcycled rubberwood and latex—is intended to put less strain on the environment and lessen carbon emissions. But that’s not the only ecofriendly aspect of this bed, as the wooden slats have felt along the side made from recycled plastics.

Thuma's Classic Bed and Essential Bed frames come in four wood stains—Walnut, Espresso, Natural, and Gray. All finishes are designed to patina, in which the wood grain and finish become much more enhanced over time. The cherry on top of this frame configuration comes in three headboard options: an all-wood headboard, a pillowboard, a cushioned headboard, or no headboard at all. The headboard interlocks with the top and side pieces, while the pillowboard is meant to be set on the frame between the mattress and the wall.

There are two upholstery options for both the pillow board and cushion, each with four color options. The Performance Linen weave is a blend of polyester, viscose, and linen, which together have a smoother feel and are woven for durability and stain resistance. Performance Linen comes in Alabaster, Natural, Light Gray, Natural, and Charcoal. Alternatively, Italian Wool Felt has a heathered look (a more color-gradient effect, with the wool’s cozy texture poking through), is stain-resistant, and is made from a blend of recycled wool, polyamide, and other fibers. The Italian Wool Felt has four similar colors to complement the Classic frame: Heathered Oatmeal, Heathered Gray, Heathered Mocha, and Heathered Charcoal.

As overwhelming as the mix-and-match options are, Thuma offers complimentary swatches so you can be positively sure. To be on the safe side with my wily, rather destructive dogs, I selected the Espresso finish and the headboard-and-cushion combination in Natural Performance Linen.

Thuma’s Classic Bed frame’s assembly process is relatively foolproof. The frame arrives in four heavy boxes, each with its contents helpfully labeled. One box contained the headboard and pillow board attachment; another, the individual legs for each corner. The last two held the bed's top, bottom, and side pieces. While each piece arrived completely wrapped and individually sealed in plastic bags, stacked within the boxes, I couldn’t help but feel that more padding was needed to better protect them. True to its ecofriendly mission, Thuma does not use styrofoam; the packaging uses recycled fiber, and the plastic coverings are recyclable (provided you have local facilities to do so). I noticed, however, a few scuffs around the bed that I did not see with the majority of the Japanese joinery frames I tested. Candidly, if I weren’t a sleep product reviewer and purchased this frame on my own dime, I would have been disappointed that it arrived in this condition.

The frame arrives with cards printed with QR codes, which lead to detailed written and visual instructions. Each piece quickly slid into place in what felt like the furniture version of Tetris. While it technically was a tool-free assembly, you’ll still have hardware to contend with in the form of six big screws (four if you skip the headboard). These are for securing the center support beam and the accent pillow attachment (should you choose to get it) to the back of the headboard.

Once the screws were hand-tightened, I unrolled the felt-lined wooden support slats. Of all the Japanese joinery bed frames I’ve tested, these were by far the heaviest and linked together as a single piece. Some frames break this portion into two parts for easier installation, but for support purposes, Thuma chose to use one. If anything, get a partner to help you with this step of the unboxing process.

I did the entire setup solo, and it took me less than an hour from unloading all the boxes to having it fully assembled. However, from start to finish, the Classic still took a bit more time to install than other Japanese joinery frames I’ve tested. This was for two reasons: the center slatted boards were heavier for me to lift, and installing the headboard cushion required some finesse, as I had to drape it over the headboard before securing it in place with two hand screws. With two people, you could easily slice that time in half.

Despite how striking it looks, this bed frame isn’t just for show. I paired it with the Thuma Hybrid mattress, a newer offering from the brand. Immediately, I noticed off-gassing circulating through my testing studio. At first, I thought it was mainly the mattress, since this is common with bed-in-a-box options that use memory foam. While the Thuma Hybrid likely contributed some to what I was detecting, it was noticeably more like a wood finish, akin to what you would notice at a woodshop or construction site. Turns out, the frame was the culprit. I popped a window open, and the issue was resolved by nightfall. Both products are GreenGuard Gold certified, which ensures clean indoor air emissions from products that off-gas.

Another surprising occurrence that started on night one of testing and lasted for several days was the frame creaking whenever I got in and out of bed. Logically, I know that the wood will settle into place over time. But there are two reasons why I call this out. WIRED Reviewer Julian Chokkattu has a Thuma bed frame, and he has noted in our guide of the best bed frames that his does not creak. Objectively, I’ve been in the mattress and sleep product industry long enough to know that product performance can vary among people—Thuma, despite all its high-quality features, is not exempt from that. But the only other Japanese joinery frame that also creaked when I tested it was the Birch Madison, the cheapest bed frame in terms of price and quality compared to the Thuma.

The brand’s high-quality standards aren’t just what put it in a league of its own. Thuma offers a lifetime warranty, the most extensive I’ve seen on any bed frame I’ve tested to date. Additionally, I would go so far as to say that if you take care of it over the years, you could easily have this bed frame for life. While Thuma is the most expensive Japanese joinery bed frame (and honestly, wooden frames in general) I’ve come across, I can’t deny that it supersedes the competition in overall bang-for-buck. Perhaps it’s time to upgrade my frame for when I’m not testing new mattresses or bed frames.
