LIFEMENT Twin Kids Mattress - 6 Inch Graphite Memory Foam Fiberglass-Free

Finding the right mattress for your child means balancing safety, support, and honest value. LIFEMENT was built on one belief: better sleep should not come with questionable chemicals or hidden compromises. This 6-inch twin mattress was designed for kids ages 3 and up, giving families a certified, fiberglass-free option they can feel confident about.
Inside, 3 purposefully engineered layers work together. A high-density base foam anchors the mattress and prevents sagging. A motion-absorbing transition layer sits above it, so restless sleepers and bunk bed siblings are less likely to disturb each other. The top layer combines graphite cooling gel memory foam with an open-cell structure that promotes airflow, drawing heat away for cooler sleep through hot summer nights and year-round. The medium firm feel, roughly a 6 out of 10, supports developing bodies across back, side, and stomach sleep positions. The 6-inch profile is sized for lighter sleepers, yet supports up to 250 lbs, growing alongside your child into the teen years.
Safety is not an afterthought. Every mattress is 100% fiberglass-free. The foam is CertiPUR-US certified, made without heavy metals, formaldehyde, or phthalates, and meets low VOC emission standards, so there is no noticeable odor right out of the box. The cover carries OEKO-TEX Standard 100 certification, confirming the fabric is free from harmful substances. The cover is removable and easy to spot clean.
This twin mattress ships compressed in a box for easy delivery and simple setup. Unroll it on any flat, sturdy surface and it is ready to sleep on the same night.

Standard twin dimensions of 75''L x 39''W fit all standard twin sheets and mattress protectors. Backed by a 10-year warranty, this is a mattress your family can count on.
