The new four-color frame version is now available.

We continuously improve our products. In 2025, all our new sheets will feature a concealed zipper design, which looks more elegant and streamlined than the previous ones with exposed white zippers. Even better, all our previous top sheets will be compatible with the new sheets; customers can simply replace the base frame to enjoy this more aesthetically pleasing design.

In June 2025, all our new sheet underframes will receive their biggest update since launch, taking the new sheet underframes a step further and going beyond just being a "simple underframe for the mattress". The updates are outlined below:

1. The pockets, which were previously located on either side of the mattress (where the thighs are when a person is sleeping), have been moved closer to the head of the bed and reinforced with stitching techniques similar to those used for sewing shirt pockets. This eliminates the possibility of tripping over or getting caught on the pockets when getting into or out of bed.
2. Previously, the ropes at the bottom of the frame had metal ends. However, if the user was not careful during the installation of the frame, the metal ends might accidentally scratch the wall. Although this is a small detail, I wanted to improve it. Therefore, I have now replaced them with soft plastic rope ends, which will not scratch the wall or other parts of the home.
3. The rope at the bottom of the frame is quite long (7-8 meters). Previously, when customers washed the frame in a high-speed washing machine, we found that the rope would sometimes get tangled or torn. This was undesirable, although the number of people affected was small. I wanted to improve the situation so that the rope would remain intact no matter how carelessly customers washed the frame. Therefore, I spent a considerable amount of time researching how to create a rope that, even at 8 meters long, wouldn't get tangled or torn in the washing machine. This new rope has been installed in the updated frame.
4. The bottom of the frame has also been fitted with brand new Japanese NIFCO rubber buckles, which make it easier to tighten the cables during installation and ensure they fit snugly against the mattress.
5. Small loops have been added to the four corners at the top of the bottom frame and the middle of both sides of the bed to fasten the latest waterproof and mite-proof mattress protector (waterproof layer). The waterproof layer is fixed between the mattress surface and the zippered mattress cover, so users can easily change the mattress cover, style, and material without sacrificing waterproof performance. Users can also remove the small loops to remove the waterproof layer for separate washing without raising the mattress.
6. Three more color options have been added, bringing the total to four, including the previous "classic gray," giving customers more choices.
7. A washing label has been added, clearly listing the cleaning method for the bottom frame.

Waterproof and mite-proof mattress protective layer

Since the launch of our new sheets in 2023, we've occasionally received inquiries from customers about the possibility of releasing waterproof sheets, and this has always been a thought in mind. Waterproof sheets aren't exactly a new concept, but the key is how well they're implemented. We don't want to produce haphazardly made products with shaky, uneven finishes. Beyond basic waterproof and mite-proof functions, we want users to be able to continue changing our various sheet styles as they like, and for this waterproof layer to be easily removed and washed independently, just like the sheet itself, without needing to lift the mattress. In June 2025, our waterproof layer will officially launch.

The waterproof layer can be attached to the four corners of the latest bottom frame and the midpoint of the two long sides.

This can be added to the homes of all guests who have purchased new sheets since the initial version in 2023 , but only if the current latest version of the bottom frame is available. ( 2025 ) The effect will be even better because the new bottom frame will have small buckles that can hold the waterproof layer in place to help with positioning.
