The right side is our Ultra Premium version, and the left side is the low-end version. The low-end versions on the market, typically priced around $1,000, usually fall into this category. Their raw materials are different; the low-end version uses eucalyptus wood from Southeast Asia, which has more knots and is heavier. In contrast, the Ultra Premium version has a thinner, sturdier wood shell with fewer knots and a uniform, naturally attractive color. Additionally, our Ultra Premium version is made with 8 layers of compressed veneer, while almost all other sellers, including HM company, use only 7 layers.
