①. Yimobra superior bath and shower mats feature 169 special big suction cups. The different suction cups have stronger adsorption than other small suction cups, which help hold in place on smooth, clean surfaces. Variety colors are available. ②. Large Size: Yimobra Square Shower Mats measure 21 x 21 Inch and provide maximum coverage. Many other mats are smaller, leaving areas of your tub exposed. ③. The mats are BPA Free, Latex Free, and Phthalate free. ④. Excellent Drainage Design: Yimobra Bath shower mats feature 149 drain holes that drain water out quickly and keep the mat dry and clean. ⑤. Machine Washable: Our durable mat is machine-washable to facilitate hassle-free maintenance and uphold its fresh appearance. We highly recommend that you wash your mat prior to use. Simply throw the mat in your washing machine on cold with gentle detergent (no bleach) and air dry. We recommend rinsing and drying your bath mat periodically to remove oily and slippery buildup that may occur from various soaps and hair products. ⑥. Warning: Prevent Falls - Secure suction cups before each use. Mat will only attach to clean, smooth surface. Not for use on textured, tiled, or non-smooth surfaces. Do not use bath oils, and jumping on the bath mat may cause slipping.
