Specifications side by side

How to choose the right Serta medium mattress

1. Match thickness to your frame

   Check the height specification to ensure the mattress fits your bed frame or foundation. The Serta Five Star Tranquility stands at 10 inches tall, making it a standard profile that fits most modern platforms. If you need a higher profile for easier entry and exit, consider the Serta Sleeptrue, which measures 12 inches. The Serta Perfect Sleeper is even taller at 13.5 inches. Verify the height dimension in the specs to avoid clearance issues with your existing bedding or frame design.

2. Select the correct bed size

   Confirm the width and length dimensions match your room and sleeping habits. The Serta Five Star Tranquility is a King size, measuring 76 inches wide by 79.5 inches long. This offers ample space for couples. The Serta Sleeptrue is a Full size, measuring 54 inches wide, which suits single sleepers or smaller rooms. The Serta Perfect Sleeper is a Queen size, measuring 60 inches wide. Always check the width and length specs to ensure the mattress fits your bedroom layout comfortably.

3. Choose hybrid or foam construction

   Decide between coil support and foam comfort based on your preference for bounce or contouring. The Serta Five Star Tranquility is a hybrid, combining coils with foam for durable support. The Serta Sleeptrue is also a hybrid, offering a similar feel with an adjustable base. If you prefer a simpler feel without coils, the Serta 10" Cooling Gel Memory Foam King uses only memory foam. Check the construction type in the attributes to understand how the bed will feel under you.

4. Consider cooling features for heat

   Look for specific cooling materials if you sleep hot. The Serta 10" Cooling Gel Memory Foam King features a cooling gel cover to help regulate temperature. The Serta Sleeptrue includes cooling coils within its hybrid build to promote airflow. The Serta Five Star Tranquility relies on its hybrid structure for breathability. Check the special features and construction details to find a model with the cooling properties that suit your body temperature needs.

5. Check for special setup features

   Determine if you want a mattress that arrives compressed or needs professional delivery. The Serta Five Star Tranquility is listed as a Bed in a Box, meaning it arrives compressed for easy self-setup. The Serta Sleeptrue is also a Bed in a Box. The Serta Perfect Sleeper is a heavy, uncompressed model, weighing 78.7 pounds, which may require assistance for setup. Check the special features to know how the mattress will arrive and how much effort is needed to get it ready.
