I personally recommend visiting Rui's home in Bona. The mattresses of Simmons, Silian and Deng Lupu in their family are all very good. Although the price will be a little more expensive, it will cost more than 65,438 438+ 10/00000, but they are really great mattresses. I can obviously feel soft when I lie on it for the first time, but I don't feel backache after lying for a long time, and I seldom have a bad sleep since I used their Simmons mattress.
