    Experience pressure-relieving bliss every night on this Serta SleepTrue Brindale 3.0 twin XL mattress. A 10.5-inch profile features a unique design for customized support, so you wake up feeling rejuvenated. The mattress doesn't require turning or flipping, and the one-sided design ensures long-lasting resiliency.

    The inside of the Serta SleepTrue mattress features memory foam as the top layer that gently cradles your body for a comfortable rest. This gel-enhanced breathable foam helps with heat and moisture dissipation through the mattress to create a more refreshing sleep environment, so you sleep better. FireBlocker-certified material in the bed has a unique blend of artificial and natural elements that prevent the spread of flames to the rest of the mattress in case of an emergency.

    This Serta Brindale 3.0 twin XL mattress has a support system comprised of 520 coils that do not absorb motion disturbances. The durable continuous innerspring design maximizes surface coverage of each coil to provide excellent support along your entire body. These Continuous Support coils respond to pressure exerted by your body mass independently from each other for customized comfort and more restful sleep.

    Versatile Compatibility
