It supports the lower back from below, maintaining a comfortable sleeping posture. The firm, resilient feel provides firm support for the body, making it easy to turn over and reducing pressure on the lower back during sleep. It's recommended for those who have found it difficult to sleep on previous mattresses due to their back or lower back sinking in. 【Premium Materials & Washable Cover】The original cover has a gentle feel and is antibacterial, anti-mite, and odor-resistant. It also comes with an inner cover to prevent deterioration of the main body and ensure cleanliness. The back of the cover has a non-slip design that prevents slipping on flooring, so you can use it with peace of mind. The outer cover can be easily removed and washed with a zipper, allowing you to keep it clean at all times. 【Compact Storage, Easy to Carry】Comes with a dedicated storage bag. It can be rolled up and stored compactly, so it doesn't take up space when not in use. It's easy for women to carry. Regarding the thickness of the mattress, please choose according to your preference. To meet the needs of our customers, we offer mattresses with different thicknesses of 3cm/5cm. 【About Mattress Creases】The mattress is rolled up and packaged, so please be sure to open it after the product arrives. After opening, leave it flat without using it until it returns to its original thickness and size. Initially, it may not be thick enough and may have creases, but after leaving it for 2-3 days, the creases will disappear and it will return to its original size. Depending on the usage environment (low temperature environment), it may take 5 days to a week. *Please be sure to open the product within one week of arrival.
