Setting up a guest room for an unexpected overnight visitor becomes effortless when you have a high-quality sleeping surface ready to unfold in seconds.

The poly jacquard cover features a slip-proof bottom to keep everything in place, though you should stick to spot cleaning to maintain the fabric. Just remember to give it about 24 to 72 hours to fully expand after unboxing, as the foam needs a little time and warmth to reach its intended 4-inch thickness.
