Premium Bed Bug Proof Box Spring Encasement - Waterproof Zippered Box Spring Cover - Ultimate Protection Against Insects, Dust Mites - Knitted Box Spring Protector (Cal King) by Utopia Bedding

I purchased this zippered Encasement to cover a new CA King 9" Metal Box Spring/Mattress Foundation/Frame. It seems to be made with quality fabric & zipper.It came with a strong *plastic-type* odor, so I washed the Encasement immediately after opening the bag it arrived in, & then dried it using the 'low warmth' (barely above 'air dry') setting, before putting it on our new box spring/foundation.The Encasement fits nicely.I appreciate the velcro 'cover' it has, that flaps over to hide the zipper-pull; this flap will protect the fabric that covers the Encasement.My only negative is that the Encasement has brown stains on it - it looks like something may have been spilled on the Encasement, prior to it being sold to me (perhaps it was someone elses return?) ..I am attaching photos to show the fit, and the unexpected stains.As the Encasement is only being used as a box spring cover (therefore it will not be seen), I am keeping the Encasement.(Knocked off just 1 star because of the stains.)

These are great matteress covers. I have a cal king with split mattress springs. It doesn’t tell you how much trouble it is to put a cal king cover on a split mattress . I finally got it on the box springs but it is really really hard. When my mattress cove comes I can only image how hard the cover will be to get on the mattress. Cal king is a very heavy mattress. But I do love these covers. They are wonderful. I love the feel and how well they fit. Just hope I didn’tmess Up my back t.trying to fit them on the bottom. I would say get 2 twins sorry I didn’t know that. Maybe they should put in ad. 5 stars!!!!!!!!!

I bought this because we had beg bugs and I wanted to secure the box springs. The encasement was delivered in a timely manner. It was delivered to an amazon locker which is convenient when you live in an apartment and you are worried about packages being taken. I was also able to go to the amazon locker at my convenience. There were no issues getting my package.When I got the encasement there were no issues with it. I stood both of my box springs vertically, slid the the encasement underneath (sliding over the top will work too), zipped up the box springs and that was it.It didn't get rid of the bed bugs but it helped.Thanks.

Work well. Just a little work getting them on.

It seems really good product, I used for the mattress and it fit right, I like it a lot, it make me feel like everything is clean, I can breathe!! my mattress was looking old and I have a dog that sleep with me ,but I didn't want to buy a new one, so this was a nice solution, it is really soft too. 😊
