I’ve tested both the BETU Mattress Bags for Moving and Storage and the DMI Waterproof Mattress Protector, and they serve very different purposes. The BETU is a dedicated moving bag made of extra thick polyethylene with 8 heavy-duty handles, while the DMI is a softer, noiseless plastic zippered cover meant for everyday protection.
If you’re moving into a dorm or storing a mattress long-term, you need to know which one actually protects your mattress from dust, tears, and moisture. I’ll break down exactly where each shines and where they fall short so you can make the right call.

Individual Product Breakdown
I tested both bags by actually packing a mattress, hauling it down a flight of stairs, and checking how well each one held up. Here’s what I found with each product.
BETU Mattress Bags for Moving and Storage

I was really impressed with the BETU bag right out of the box. The extra thick polyethylene material feels tough and the 8 heavy-duty handles made carrying my mattress up a narrow staircase way easier than I expected. The 3/4 side zipper opens wide so you can slide a thick mattress in without fighting it, and the opaque black color hides your mattress if you’re storing it in a shared space. My only gripe is the zipper seam isn’t fully waterproof, so I wouldn’t trust it in a flood-prone basement, but for moving and normal storage it’s excellent.
✅ Pros
- 8 heavy-duty handles make carrying up stairs a breeze
- Extra thick waterproof PE material keeps dust and moisture out
- Reusable and eco-friendly, so you get more than one move out of it
- Clear ID card slots on both sides help you find the right size fast
❌ Cons
- Zipper seam is not fully waterproof, so avoid puddles
- Only available in black and gray, no white option

The DMI protector is a different beast entirely — it’s built for everyday use on your bed, not for moving day. I like that the plastic is noiseless and won’t crack or peel over time, which is rare for a waterproof cover. But here’s the catch: the Twin size only fits mattresses up to 8 inches deep, which means most modern mattresses won’t fit at all. It’s great for protecting against spills and bedwetting if you have a thin mattress, but I wouldn’t use it for moving or storage since it lacks handles and the material is much thinner than the BETU.
✅ Pros
- Noiseless plastic that won’t crack, peel, or harden over time
- Machine washable for easy cleaning after spills
- Very competitively priced, especially for the Twin size
❌ Cons
- Only 8 inches deep — won’t fit thicker modern mattresses
- No handles, so it’s terrible for actually moving a mattress
- Thin plastic offers less protection against tears during transport
Which One Should You Buy?
Look, I know it’s tempting to just grab whatever’s cheapest, but these two bags serve totally different jobs. Here’s who I’d send to each one.
BETU Mattress Bags for Moving and Storage is right for you if…
- You’re moving into a dorm and need the 8 heavy-duty handles to haul a mattress up stairs
- You’re storing a mattress long-term in a shed or attic and need extra thick waterproof PE material
- You want a reusable bag that can handle multiple moves, not a one-time plastic wrapper
DMI Waterproof Mattress Protector is right for you if…
- You need a noiseless mattress protector for everyday bedwetting or spill protection at home
- You have a thin mattress that’s 8 inches or less and just want a waterproof zippered cover
- You’re on a tight budget and don’t care about moving handles or heavy-duty protection
❌ Who Should Skip All of These?
If you have a thick pillow-top mattress over 13 inches deep, neither of these will work well for you. The BETU handles it at 13.5 inches, but the DMI at only 8 inches won’t even fit. You’d be better off looking for a heavy-duty moving bag specifically designed for extra-thick mattresses.
For most people moving or storing a mattress, I’d grab the BETU every single time. The 8 handles alone make it worth it, and the extra thick material gives you real peace of mind that your mattress won’t get torn or dirty during the move.
Frequently Asked Questions
Which is better for moving a mattress: BETU or DMI?
The BETU is way better for moving, and it’s not even close. The 8 heavy-duty handles make carrying a mattress up stairs actually manageable, and the extra thick polyethylene material resists tearing when you’re wrestling it through doorways. The DMI has no handles at all and the plastic is thinner, so I wouldn’t use it for anything beyond protecting a mattress that’s already in place.
Is the BETU mattress bag worth the extra money over the DMI protector?
If you’re actually moving or storing a mattress, yes, absolutely. The BETU is built for that job with its thick PE material, 13.5-inch depth to fit modern mattresses, and those handles that save your knuckles. The DMI is cheaper but it’s really just a basic waterproof cover for everyday bed use, not a moving bag — so you’re paying for a completely different product.
Can I use the DMI mattress protector for storage in a basement or attic?
I wouldn’t recommend it for long-term storage. The DMI is only 8 inches deep, so many modern mattresses won’t even fit inside, and the thinner plastic can tear if something rubs against it in storage. The BETU’s extra thick material and opaque black design are much better suited for basements, attics, or sheds where dust and light exposure are concerns.
Which one has better waterproof protection?
Both are labeled waterproof, but the BETU’s extra thick polyethylene material gives me more confidence for storage situations. That said, the BETU’s zipper seam isn’t fully waterproof, so if you’re worried about standing water in a basement, neither is perfect. The DMI works fine for everyday spills on a bed, but I’d trust the BETU’s thicker material more in a storage environment.
Which bag is better for college dorm move-in day?
The BETU is the clear winner for dorm move-in. It’s literally described as a “dorm room essential” and it’s an Amazon’s Choice product with 4.7 stars from over 1,000 reviews. The 8 handles make it easy to carry a mattress through crowded hallways, and the clear ID card slots help you spot your bag among a pile of similar ones on move-in day.
Can either of these bags be reused for multiple moves?
The BETU is designed to be reusable and made from eco-friendly PE material that holds up well. I could easily get two or three moves out of one bag if I’m careful with it. The DMI is really meant to stay on your mattress as a permanent protector and the thinner plastic won’t survive being taken on and off repeatedly for moves.
My Final Verdict
The BETU Mattress Bag is my clear winner for anyone moving or storing a mattress. Those 8 heavy-duty handles and the extra thick polyethylene material at 13.5 inches deep make it a purpose-built moving tool, not just a plastic sack. The DMI is a decent everyday waterproof protector for a thin mattress, but it’s not a moving bag and shouldn’t be used as one.
If you’re still on the fence, ask yourself one question: are you actually moving this mattress somewhere, or do you just want to protect it while you sleep on it? If you’re moving, get the BETU. If you just need a basic waterproof cover for a thin bed at home, the DMI will do the job for less.
