Reviews
What people who already sleep on it say.
11 reviews from customers
The first 100 nights
A mattress cannot be judged in five minutes.
That is why the trial is 100 nights, not 10. This is what usually happens.
Delivery
You get a date notice before delivery.
First night
Your body is still used to the old mattress. Feeling strange is normal.
Adjustment
Typically, the body adjusts within 14 to 21 nights.
Decide
If it is not right, we collect it at no cost and refund you.
Who it is for
The Kaizen is for you if...
✓ You like the feeling of being cradled by the mattress
✓ You sleep on your side or change position
✓ You prefer a mattress without springs: quieter, warmer
✓ You want Dreamura quality at an accessible level
If you need firm support for lower back pain, see the Hisui.

What the Advisor says
“For those who want to feel cradled by the mattress.”
When someone tells me they want to feel cradled by the mattress, I recommend the Kaizen. It has the right memory foam for that effect without crossing into excessive softness — and it is what many customers ask for without knowing the technical name.
— Ana Cristina, Sleep Advisor
Frequently asked questions
Before you order.
Compared with the Kumo?
The Kaizen has more layers and a more enveloping feel. The Kumo is simpler, firmer and cheaper.
Does it get hot?
Traditional memory foam gets hot. Nemuri Comfort was developed to be more breathable. In very hot climates, a cooling topper helps.
Is it recommended for couples?
Yes. The foam absorbs movement — one person moving does not wake the other.
Is it suitable for back pain?
For comfort, yes. For lower back pain requiring firm support, the Hisui is the right choice.
How long does it take to adapt?
14 to 21 nights.
