Couples with different sleep preferences is one of many reasons a split king is a great mattress selection, and they’re compatible with adjustable beds. Split king mattresses allow you to adjust the bed to your preference without disturbing the comfort of your sleep partner, unlike standard king-size beds.
A split king mattress is the same size as a king-size bed, except it is two twin XL mattresses next to each other instead of one solid king mattress. Sealy Posturepedic Beech Street Plush is plush with the firmest mattress support in the new addition to the Sealy line up where they have taken the higher end features found in more expensive beds and brought them down to a more affordable price. If you are looking to get the most for your money and like a plush mattress with firm support, this is the bed for you!
The Sealy Response Performance Beech Street Plush gets its firmness from the CertiPur-US certified foams that are designed to provide a comfortable level of pressure point relief without sacrificing a harder feel.
Something previously restricted to the higher end product line, this mattress features a posturized center third. This is a reinforced band of Gel Memory Foam in the center third of the mattress to give additional support to keep you from waking up with a sore back.
World Class Support
Using the same coil system found in beds that cost hundreds more, this individually wrapped coil system uses hundreds of independently supportive coils to reduce motion transfer and give you deep down back support.
Best Value for any budget
This mattress takes most of the hallmark features of the higher end beds in the Sealy Performance line like a high count coil system, reinforced Posturepedic center third, and a coil edge support system to provide arguably the best mattress for the money on our entire site.
