Designed particularly for Tesla Model 3, 100% fit, can be stored in the hidden trunk or in the frunk. Space saving.
Two kinds of foams applied, high density foam and memory foam. More supportive yet still compressible to be stored in the bottom trunk.
We make the storage bag a real cooler which can keep drinks/food cold/fresh up to 24-48 hours, depending on how much ice you use.
Cube ice in the cooler/insulated bag won't melt up to 12-24 hours. More importantly, when the ice melts, the bag won't leak.
High count thread cotton sheet makes a huge difference as well. We upgraded the sheet too. It's very soft, super comfortable fitted sheet for the camping mattress is provided. Beat all similar camping sheets out there.
The foam we use responses fast. We make the mattress 2.16" in the factory. We can't make it thicker otherwise the carrying case can't be zippered and can't be stored in the bottom trunk. When you just received it, it has been squashed in the bag for maybe 2 months. It will expand to this thickness after a week or so by not compressing it.
Though it sounds like 2.16" is thin, it's supportive enough as we use the high density foam. Other sellers may say their mattress is 2.6" but their foam is too soft. We did the comparison for you. 2.6" soft foam is not as supportive as the 2.16" high density foam. We want to make the high density foam 2.6", but the storage in the bottom trunk doesn't allow. High density can't be too thick otherwise it can't be compressed. But trust us, the 2.16" high density foam is supportive enough.
