About this item

• After-sales Service: ONBRILL is committed to customer satisfaction. If you encounter any issues, please do not hesitate to contact our customer service team. We are fully committed to offering you the perfect service
• Internal Materials and Construction: The comfort layer uses a wave sponge, which is conducive to ventilation and breathability. Adding a high elasticity sponge layer is more conducive to fitting your body and dispersing the pressure. The pocket spring provides good support for your body, which can maximize the relief of lumbar, back, and leg pain
• Fiberglass-Free Bed Mattress: The ONBRILL hybrid mattress is carefully designed according to the human body curves and made of high-quality fiberglass-free materials to provide you with a comfortable and healthy sleeping experience. The mattress support layer is medium firm, making it an ideal mattress choice for all types of sleepers
• Motion Isolation & Edge Support: The mattress's pocketed coil construction absorbs motion and minimizes motion transfer for a comfortable night's sleep. Thicker springs on the edges of the mattress solve the problem of sliding around the edges. Differential rebound between the edges and center of the bed makes the mattress smoother and more comfortable
• Measurements: 75 inches in length, 54 inches in width, and 12 inches in height. To start using, place the mattress flat in a well-ventilated space for 48-72 hours until it expands completely. If exposed to cold temperatures, it may require additional time.
• Certified Mattress: Full-size memory foam mattresses not only have the CertiPUR-US certificate (which measures odor, material, performance, and durability) but also the rigorous certification from OEKO-TEX and fire testing
• Comfortable & Breathable: High-weight knitted fabric is skin-friendly and soft; the unique pattern on the surface is more comfortable and breathable, allowing you to enjoy a cool sleep. Gray and white color is more advanced
