【Quality sassafras wood seat】Different from other normal wood materials, our stools adopt the sassafras wood, which has a strong sturdiness, high density, good oxidation resistance and shock resistance. 【Sturdy X-frame】There is an X-shaped metal frame beneath the seat that ensures the stability of the stool. Moreover, the plastic pads on the X-shaped crossbars protect the wooden seat from scratches or scuffs when stacked up. 【Ergonomic backrest design】With a low backrest design, our chairs provide you with good lower back support and take off some of the stress on your back. The backrest barstools also feel more secure when you have a supporting surface on the back.
