Excellent Solution to Medical Emergency

My husband was in the hospital with severe abdominal pain, possible diagnosis of cancer to come. Needed to establish ground-floor bedroom in a small space. Found this extra-long twin mattress, memory foam (new to us), perfect firmness, adjustable, just excellent!
