Ok I’ve realized that my current mattress foundation (Ironwood mattress foundation, that was recommended here at some point) transfers significant amounts of motion. I tested my mattress on the floor for one night, where it had absolutely zero motion transfer, whereas on the foundation it has noticeable motion transfer.
After doing some research, Thuma came up as an often recommended bedframe/foundation that’s rock solid. It just arrived today, and I set it up, and it’s a wobbly mess. The japanese joinery is way too loose on all sides and it moves freely. Such disappointing quality for the cost.
So now I need to look again. I saw that Terra foundations are considered very solid, but they don’t offer a return policy, so I don’t want to risk buying from them if it turns out it’s not solid enough for my requirements.
What are some of the most absolutely solid bedframes/mattress foundations out there that would also have decent trial periods?
Thanks. Looks like the Big Fig is also Japanese joinery, so that could have the same risk of being loose like the Thuma.
The embrace looks super solid, but it’s too bad they don’t use slats for the mattress support, as that will minimize ventilation (and my current mattress is optimized for ventilation, as I sleep hot, and requires slats to have it ventilate well).
I’ll look into the other two. Thanks for the tips!
If you want one that offers a great value for a Japanese joinery, that can stand toe to toe with Thuma without the wobble, is the Flexispot Kana bedframe. They have redesigned it to be even better. There is one caveat. Right now until their 3.0 version comes out, you have to buy their 2.0 slats, which are 3/4" thick and under 3" spaced. The slats the bed comes with is currently 1/2" thick, which is not bad, but 3/4" is certainly better. I have 2 of their original Japanese Joinery beds I use for testing mattresses. They are solid, have recessed legs so you dont bump into them and the frame does not wobble at all (at least mine dont).
For the price it is a bargain compared to Thuma, even with the extra slats.
Oddly enough, I have the ironwood 5" foundation, the all wood one, not the one with the plastic corner connections, and I have no issues with mine on our master bedroom king mattress. If the Terra had be available when I bought the Ironwood, there would not have been any debate, the Terra is the tank of foundations.
Thanks. I’m reluctant to buy the Terra as they don’t offer any trial period. So I don’t want to risk it.
And my Ironwood foundation has the plastic corner connections, and that could very well be the culprit, where over time it might start to flex a little bit.
I’ll check out the Flexispot as it’s a lot more affordable than the two alternatives the other poster mentioned.
So I ended up buying the Sleeping Duck Indestruct bed, and I can say it’s an extremely rock solid frame. Like extremely so. Solid steel construction with steel beams, weighs like 350lbs. Ridiculously heavy, doesn’t budge a millimeter. And that has solved my motion transfer problems.
