Key item features

  • 𝐏𝐑𝐎𝐓𝐄𝐂𝐓 𝐘𝐎𝐔𝐑 𝐖𝐇𝐎𝐋𝐄 𝐁𝐄𝐃– We often worry so much about protecting our mattresses, but we neglect buying a protector for our box springs. Your box spring is just as susceptible to moisture and water damage as your mattress, so why not protect it with our zippered encasement.
  • 𝐙𝐈𝐏𝐏𝐄𝐑𝐄𝐃 𝐏𝐑𝐎𝐓𝐄𝐂𝐓𝐈𝐎𝐍 - With our super zipper closure fully encasing your box spring, everything will stay out completely! Our smooth gliding, tight locking zipper will protect your box spring on all six sides.
  • 𝐏𝐄𝐑𝐅𝐄𝐂𝐓 𝐅𝐎𝐑 𝐇𝐔𝐌𝐈𝐃 𝐂𝐋𝐈𝐌𝐀𝐓𝐄𝐒– High heat and humidity can allow moisture to collect inside your box spring, causing major damage. Why risk damaging your box spring when you could protect it instead?
  • 𝐖𝐀𝐓𝐄𝐑𝐏𝐑𝐎𝐎𝐅 𝐏𝐑𝐎𝐓𝐄𝐂𝐓𝐈𝐎𝐍– Smooth, soft and durable fabric material backed by a waterproof inside layer. Featuring a zipper closure, it will prevent harm and damage to your box spring.
  • 𝐄𝐀𝐒𝐘 𝐂𝐀𝐑𝐄 – Machine wash in cold water with mild detergent. Tumble dry and remove promptly when done. Do not iron or apply heat, as it could damage the waterproof layer.

Great Water-Proof Box Spring Cover for Queen Bed

I liked how easy the box spring slid into the cover. The cover leaves room around the box spring so that it won't easily tear when moving and adjusting to fit into the bed frame.

Mattress and Bid Springs zip cover

I love the fact that it zips to prevent from coming off. Having these covers does mean the top mattress will slide around verses staying in place but least everything is protected.

Box Springs encasement

This product is well Made! Zippered for easy fit and easy to get on the box spring! Material seems very durable! Much better quality than my previous Bo's spring encasement! Wouldn't hesitate to purchase again! Bought the XLTWIN!
