Cooling Technology
The GhostBed Flex 3D Matrix uses a 3D matrix layer that promotes air circulation. This layer sits between the comfort foams and the coil core. Gel-infused memory foam also draws heat away from the body. Owners report sleeping cooler compared to traditional memory foam. The breathable cover adds to the cooling effect.
Firmness and Support
This mattress rates as medium-firm, around 6.5 out of 10. It provides a balanced feel that supports spinal alignment for back sleepers. Stomach sleepers benefit from the firm surface that prevents hips from sinking. Side sleepers may find it too firm, leading to pressure points. The coil system offers zoned support, with firmer edges and a softer center.

Questions before you buy
How does the 3D Matrix layer work?
The 3D Matrix layer is a breathable, open-cell material that allows air to flow freely. It also adds a slight bounce, making movement easier. This layer helps regulate temperature and reduces the heat retention common in memory foam.
Is the GhostBed Flex 3D Matrix good for side sleepers?
Most side sleepers need a softer mattress to cushion shoulders and hips. This mattress is firmer, so it may not provide enough pressure relief. If you're a side sleeper, consider a softer model or a topper.
Does it have good motion isolation?
The individually wrapped coils reduce motion transfer, but not as well as all-foam mattresses. Some owners report feeling movement when a partner tosses and turns. If you share a bed, this might be a consideration.
What is the warranty and trial period?
GhostBed offers a 101-night sleep trial and a 25-year limited warranty. This gives you ample time to test the mattress at home. If you're not satisfied, you can return it for a full refund.
Is the mattress heavy?
Yes, the GhostBed Flex 3D Matrix weighs around 100 pounds for a queen size. This makes moving and setup a two-person job. Plan ahead for delivery and placement.
Can I use an adjustable base with this mattress?
Yes, the mattress is compatible with adjustable bases. The hybrid construction bends without damaging the coils. This adds versatility for those who want to elevate their head or feet.
How does it compare to the GhostBed Classic?
The Flex 3D Matrix is firmer and has better cooling than the Classic. The Classic is a medium-firm all-foam mattress, while the Flex is a hybrid. The Flex also has better edge support and responsiveness.
Does it sleep hot?
No, owners report that it sleeps cool. The combination of the 3D matrix, gel foam, and breathable cover promotes airflow. This makes it a good option for hot sleepers.
