**Q: What are the dimensions of the cover?**
A: Twin Size Box Spring Encasement	38" x 75" x 9"		Twin XL Size Box Spring Encasement	38" x 80" x 9"	Full Size Box Spring Encasement	54" x 75" x 9"	Full XL Size Box Spring Encasement	54" x 80" x 9"		Queen Size Box Spring Encasement	60" x 80" x 9"King Size Box Spring Encasement	2 38" x 80" Cal King Size Box Spring Encasement	2 36" x 84" encasements

**Q: Is the entire cover (all 6 sides) waterproof? or just the top?**
A: The encasement is fully waterproof on all 6-sides.  Hope this helps.

**Q: Would this work on a low profile queen split box**
A: If you have a low profile box spring make sure to order a low profile size. I ordered the regular box spring size encasement and it was way to saggy.

**Q: Would this cover be baggy on a full mattress?**
A: As long as you order the Full Size mattress cover it should fit fine.  I have ordered both Queen and King sizes and they have both fit perfectly.  Good Luck!
