Our take on the 8 Inch King Size Mattress, Cooling Green Tea Gel Memory Foam Mattress in a Box

The Beddle 8 Inch is a king-size memory foam mattress in a box, built with gel-infused memory foam over a high-density support base and finished with a removable zippered cover. It targets a medium-firm feel that suits back, side and stomach sleepers, with cooling gel and breathable foam aimed at temperature control and a non-slip bottom to keep it in place. The foam is CertiPUR-US certified, and the mattress ships compressed and expands over 24 to 48 hours. At 8 inches it is a thinner, simpler build than 10 to 12 inch foam mattresses, so it suits guest rooms, bunk setups and budget-focused buyers more than shoppers wanting a plush, deep mattress.

Questions and answers

Is the Beddle 8 inch mattress good for side sleepers?
Its medium-firm memory foam contours the shoulders and hips, which suits many side sleepers. Very light side sleepers may want a softer topper.
Does the gel foam actually sleep cool?
The gel infusion and breathable foam are designed to improve airflow and limit heat buildup. It runs cooler than plain memory foam, but it is still a foam mattress.
How long does it take to expand?
Unbox and unroll it, then allow up to 24 to 48 hours for full expansion. It is usable sooner but reaches full height later.
Does it work on an adjustable bed base?
It is a flexible foam mattress, so it can bend with an adjustable base. Check your base's weight and size limits for a king.
Is the cover removable and washable?
The soft cover has a zipper and can be removed for cleaning. Follow the care instructions on the cover.
Is the foam certified?
Yes, the foam is CertiPUR-US certified for low emissions and durability.
