Question 1

What are the exact dimensions of this mattress, and will my current twin sheets fit?

Accepted Answer

This mattress measures 80"L x 38"W x 15.25"H. Because a twin XL is five inches longer than a standard twin, you will need to purchase "Twin XL" specific sheets. Standard twin sheets will not stretch enough to accommodate the 80-inch length. Additionally, with a luxury profile of 15.25 inches, we recommend deep-pocket sheets to ensure a secure fit over the reinforced edges.

Question 2

Is this mattress suitable for a tall adult or a college student in a dorm?

Accepted Answer

Yes, the twin XL size is the industry standard for taller individuals and is the most common size found in college dormitories because it provides the extra legroom needed for adults. However, at 15.25 inches thick, this mattress is significantly taller than a standard institutional mattress. If using this for a dorm or a lofted bed, we advise measuring the height of your bed rails or headboard to ensure the profile fits safely and comfortably within the space.

Question 3

Can I use this mattress with an adjustable power base?

Accepted Answer

This mattress is fully compatible with adjustable bases. Its construction is designed to flex with the base's movements, which can help with lifestyle needs such as reducing snoring or finding a more comfortable position for reading and watching TV. For those looking to create a "Split King" setup, two of these twin XL mattresses can be placed side-by-side on a king-size adjustable base to provide individual comfort and control for both partners.

Question 4

What is the policy if the mattress feels too soft or too firm after I buy it?

Accepted Answer

Based on our 90-night Mattress Sleep Trial, we require an initial 30-night adjustment period to allow your body to get used to the new support system. If you are still not satisfied after the first 30 days, you can request a one-time exchange between day 30 and day 90 of delivery. Please note that exchange fees apply, and the mattress must be in its original, clean condition to qualify for the trial.

Question 5

What kind of support does the innerspring system provide for back pain or motion transfer?

Accepted Answer

This mattress is engineered with Triple-Stranded Pocketed Coil Technology, which provides our highest level of individualized support. Unlike traditional interconnected coils, these pocketed coils move independently to contour to your body's specific shape and significantly reduce motion transfer. This makes it an excellent choice for those seeking pressure relief for the back and hips while ensuring that movement on one side of the bed doesn't disturb the other.

Question 6

How does this mattress manage heat for someone who tends to sleep hot?

Accepted Answer

This model utilizes a multi-layered approach to temperature regulation. It features a cooling cover integrated with specialized vertical fibers and surface-cooling technology to transfer heat away from the body. Internally, the mattress contains Micro Diamond Memory Foam, which is infused with actual diamond particles to leverage their natural thermal conductivity and move heat away from your sleep surface throughout the night.
