About This Product

Give yourself the perfect stage for a good night's sleep with this mattress. Crafted using individually wrapped pocket coils and a quilted foam topper, this mattress is perfect for giving you the support you need with a medium-firm feel. Plus, it's both breathable and has low motion transfer, so you can keep cool and rest easily without distractions. This mattress is backed by a 10-year warranty and arrives compressed in a box, so we recommend giving it a moment to expand before using it.
