There is a bed called the Cuddle Mattress that it is divided into layers of foam for your arm to slip though.
The Cuddle Mattress Has Arm Slots Built Into Its Foam
Anyone who's ever tried to cuddle for more than ten minutes knows the struggle: you want to be close, but your arm is trapped under your partner's weight, slowly going numb. Enter the Cuddle Mattress, a bed that actually acknowledges this very specific problem exists.
Instead of being one solid slab like normal mattresses, this one has slatted sections at the head and foot where individual foam strips sit side-by-side like books on a shelf. You can slip your arm down between the slats, so the weight rests on the mattress itself rather than cutting off your circulation.
Three Layers, One Mission
The construction uses three distinct foam layers throughout: a 2-inch comfort layer on top, a 5½-inch high-density support core in the middle, and a 1-inch base layer. The slats at each end are made from these same layers but cut into individual strips connected by metal rods.
There are six slats per end, giving you options depending on your cuddling configuration. The middle section stays solid for conventional sleeping when you're not wrapped around another human.
Memory Foam Meets Romance
The original version uses standard polyurethane foam, but there's an upgraded model (the MPU) where both the top comfort layer and bottom base layer are gel-infused memory foam designed to dissipate heat. Because apparently getting sweaty while your arm slowly dies wasn't enough of a challenge.
The whole thing is also flippable. Put the thicker comfort layer up for a medium feel, or flip it to use the thinner base layer on top for medium-firm support. It's like getting two firmness options and solving the cuddling problem simultaneously.
Does It Actually Work?
Reviews suggest the concept works better in theory than practice for some couples. The slats can shift slightly, and you need to assemble them yourself using those metal connector rods. But for side sleepers who genuinely want to maintain contact without sacrificing arm function, it's one of the few mattresses that even attempts a solution.
The design acknowledges something most mattress companies ignore: people don't just sleep alone in rigid positions. Sometimes they want to be close without experiencing temporary paralysis as the price of intimacy. Revolutionary concept, really.
