Thanks for your question Xenia. In general, the type of mattress itself may not provide the best solution to this problem. A better and more cost-effective solution would be bedbug-proof mattress covers.

These full-encasement mattress protectors go all the way around the entire mattress (covering all 6 sides of the mattress, not just the top), to make sure bed bugs have no way of finding their way into the mattress. The best ones go beyond that by using zippers with extra-fine teeth to make sure bed bugs can't get through the teeth of the zipper. They also have special zipper enclosures to make sure bed bugs can't get in through the tiny space at the very end of the zipper.

Assuming you can start from bedbug-free mattresses, these cases are designed to keep any bed bugs from getting into the mattress in the first place. However, if you already have bed bugs, these cases can also keep the existing bed bugs trapped inside the mattress, eventually causing them to die of starvation since no food source exists for them inside the mattress.

Here are the two best options we'd recommend. Both of these can be purchased through Amazon, and either of them should be very effective at addressing your bed bug problem. These are the links to the queen-size versions so be sure to select the correct size before you purchase.
