Sealy mattress-in-a-box models bring trusted comfort and supportive sleep technology to a convenient boxed delivery experience. Designed with pressure-relieving foams, responsive support and durable construction, Sealy memory foam and hybrid mattresses can help create a more comfortable sleep surface for a wide range of sleepers. Memory foam options contour to the body to help relieve pressure around the shoulders, hips and back, while Sealy hybrid mattresses combine conforming foam with individually wrapped coils for a balanced feel, responsive support and airflow. With choices in plush, medium and firm comfort levels plus twin, full, queen, king and California King sizes, it’s easier to find a Sealy mattress that fits your sleep style, bedroom and budget. A Sealy mattress-in-a-box can also make mattress shopping and delivery more convenient, especially for shoppers looking for a quality mattress without traditional showroom delivery. After the box arrives, carefully unbox the mattress, place it on a compatible foundation or bed frame and allow it to expand according to the manufacturer’s instructions. Consider your preferred sleeping position, firmness level, pressure relief needs and motion isolation before choosing the right Sealy model. Sleep Experts® at Mattress Firm can help you compare Sealy bed-in-a-box options with other mattresses, answer questions about setup and delivery and find comfortable support for better zzz's.
