I can use a mattress like this “love mattress”. There have been times, when I wished the mattress provided more “traction” and a place to anchor the foot for all the activities one might want to indulge in. Especially if you or your lover is in to satin sheets, you want to push but you just slide off! And how often you want to snuggle up but the positioning is always awkward.
This would be perfect.

Mehdi Mojtabvi’s Love Mattress offers a simple solution. A solid unit makes up the middle portion of the bed, with several adjoining strips of foam connected at either end. Between these slats one can drop their shoulder or arm, allowing for a much more comfortable sleeping position while remaining all snuggled up. The whole mattress can be covered in standard linen. Not bad!
When can I try it out?
