Can I do laundry?

The ultimate warmth duvet that eliminates the need for feathers or blankets

Can it be put in the dryer?

Do not tumble dry. Line dry in the shade.

Can I use a futon dryer?

Yes, you can. However, please avoid using it on top of the Brain Sleep mattress or near the Brain Sleep pillow as it may cause the shape of the product to change.

What colours are available?

Available in two color schemes: cosmic blue and light gray.

Do you have a special duvet cover?

It can be washed in a home washing machine and is reversible, so you can use it without a cover. There is no part to tie the strings of the cover.

What season is it used?

Basically, use it as an inner blanket under a thick duvet with the warm side facing you in spring and autumn, the cool side facing you in summer, and the warm side facing you in winter. Depending on the temperature, you can use it alone or with other bedding.

For sleeping in the car

Purchased mainly for use in a camper <br>It doesn't get fuzzy, it doesn't take up much space, and it's stored in a special bag so it looks neat and tidy. It's also washable, which is nice. I like the light grey color, which is a nice touch.
It's convenient to wear one piece all year round <br>I also purchased one for home use. <br>The whole family uses it

Lightweight and easy to use

It's light and feels good on the skin, so you can use it without any stress even when the air conditioner is on.

The dirt won't come off

I purchased the light gray one on 10/30/2023.
Currently, the part of my summer pants (nylon side) near the face is yellowed. I inquired about it and received an email with instructions on how to remove it using an enzyme bleach. I used a strong product called "Oxyclean", but it didn't come off. I realized that it's difficult to remove stains from nylon.
It's only been a year since I bought it, and I never expected it to get so dirty and that it would be impossible to remove. I don't want to continue using it, so I feel like it's a big expense. If you're worried about yellowing, I recommend not buying it.

It's light and doesn't cause stress when you sleep.
It can be used reversibly, but it's hard to tell because the colors are the same.
I think it would be easier to understand if we made our current products reversible in two colors.

Sleep REMNEME

It was cold. I had been using Perfect Warm EX in combination with a winter mattress pad, and it sometimes felt a little hot in early spring, so I bought the All Seasons. However, even in early spring, on days when the temperature was low, I was cold and couldn't sleep well. In the end, I ended up using Perfect Warm EX in combination with a summer mattress pad for a while. Since then, as the temperature has risen, I have had more opportunities to use the All Seasons, but I would like the warmth of the All Seasons to be improved and made a little warmer.
