• Get the best of both worlds with this dual support, medium comfort level mattress. This hybrid mattress consists of pocket spring coils and two layers of memory foam padding. The combination of pocket springs and memory foam padding allow a supportive contoured rest. No need to purchase a memory foam topper with the padding already built-in. Pocket spring coils are individually wrapped springs that act independently, providing superior motion isolation and support to the contours of your body. The handles will help you move the mattress around easily.This mattress is perfect for a platform bed or trundle. The mattress can also be placed on adjustable bed frames. Requires foundation or box spring with the use of a standard bed frame. Once you cut the plastic, the mattress will start expanding! Your mattress will return to its original shape in 2 to 5 days. The memory foam padded mattress adds a barrier between the springs for a quality night''s rest. You can prolong the lifespan of your mattress by acquiring a mattress protector. • King Size Mattress• Tight Top Bed Mattress• Memory Foam Padding• 10" Pocket Spring Coils• Pocket Coils reduce motion transfer• 6.5 Gauge Springs• Foam Cushioning• Medium Firm Comfort• Bed Handles provide easier movement• Designed for Platform Beds and Trundles• Please allow 2 to 5 days for mattress to fully expand• Single Unit Weight: 122 lbs• Item Width: 75.5 Inches• Item Depth: 81 Inches• Item Height: 12 Inches• Weight Capacity: 1100 lbs
