Ultrablock mattress bag

Are you moving soon and need to protect your mattress? A mattress bag can help.

I've moved a lot of mattresses. For 3 years I picked up mattresses for a company. So I've purchased so many mattress bags. I know the importance of a good quality mattress bag that won't tear easily.

A thicker mattress bag will protect your mattress – because mattresses are easy to get dirty and expensive to replace. Your mattress can easily get damaged from moves or storage so you do always want to protect it.

I was provided the Ultrablock Mattress Bag for this review and may earn a commission when you shop through my links.

Ultrablock Mattress Bag Review

The Ultrablock mattress bag is a bestselling mattress bag on Amazon. It's made of 6 mil plastic. It's a heavier duty plastic so this will protect your mattress or your box springs (or both) if they're not too thick.

You can buy mattress bags at most moving stores but they are quite thin and flimsy and will tear easily. We reviewed a queen size mattress bag.

In the video, I'll show you how thick the Ultrablock mattress bag is. You can either remove all bedding or could leave the sheets on although I wouldn't if you wanted to keep them on so you won't have to make the bed and protect them but for this review, I removed everything. Put the longer end underneath and shimmy it up.

If you keep your mattress in your garage, a storage unit, in the back of a moving van or even the back of a truck, the Ultrablock mattress bag will protect it. Therefore, you'll be prepared for things like weather (rain or snow), dirt, dust, rodents or insects.

It has 2 wide adhesive strips on one edge that you just peel off and seal. No need to use packing tape. And also, the adhesive strip prevents the bag from blowing off while you drive. This is especially important if you have an open truck or if you put the mattress on top of your vehicle.

Size and Dimensions

This mattress bag is 54 inches by 97 inches by 16 inches thick. That means it will fit any mattress or box spring 15 to 16 inches deep.

The Ultrablock mattress bag is also reusable. You should be able to get at least three uses out of this. It also can be used as a vacuum pack mattress bag if you have a vacuum cleaner.

Sometimes some sellers say a mattress bag is a 4 mil or 6 mil or even an 8 mil, but it's really actually thin, cheap polyurethane. This Ultrablock mattress bag is not going to tear easily. It's pretty thick and the size of the bag can accommodate quite a bit more.

You can also opt to throw your all bedding in, your pillows or anything that you need to stay protected along with your mattress and keep them together. I've done that before.

How to Use

Seal the mattress bag so that there's a several inches allowance. Peel off the backing by pressing them together. You can also choose to use only one of the adhesive strips so that we can easily reuse the mattress bag.

Fold the unpeeled side to get a nice tight fit and stick the peeled side on the other side of the mattress bag. If you choose to use both the adhesive strips and decided to reuse the bag, it's possible that the tape may not be sticky any more. Or, there may be tears on the plastic. In that case, just use some packing tape to seal the gaps.


15 year limited warranty. This is the first time I've seen a warranty of any length on a mattress bag.

The Difference Between a Mattress Bag and a Mattress Protector

A lot of people get a mattress BAG and a mattress PROTECTOR mixed up. A mattress bag is not to sleep on. It's for storing your mattress, to keep it clean, keep pests spills or dust off of it or even allergens. It's made of plastic or something like a tarp material.

A mattress protector is made of fabric and that protects your mattress when you're sleeping on it. It's to help prevent pee, blood or other things from staining your mattress (since you can't easily clean one or put it into the wash). So you just remove and wash the mattress protector and then put it back on.

So overall, this mattress bag is good quality. It will likely be reusable 3 or more times, as long as it doesn't get a lot of holes. You can always patch those up with packing tape. So that is my review of this mattress bag. The thickness and the sealed edge make it superior to a lot of mattress bags we've tested and it will definitely protect your mattress.
