Double mattress or 2 same single beds are required!!!

Mi VPO, infection in the IF region. A double mattress is also needed, or 2, however, from single beds ... The sofa is old, it is impossible to wash the springs, it is simply impossible to sleep. Please help me. Sleep on the sofa for summer dads, mami has osteoporosis. Such a faraway. Even if it’s not costless, then it’s not for a penny of the world, be kind ... We can take it ourselves.
