These bags hold a tri-fold twin with ease and leaves a bit of room for a pillow and sheets. Rollers are a bit wobbly but do the job.

Perfect fit for the mattress I bought. The rollers make it so much easier to transport. The zippers on each side work great also!

My daughter said it was very comfortable. I wasn’t sure if she was just being polite. So I tried it out. It really was. I did however also buy a high quality mattress cover with 2 inch foam and puffy fabric. It really was excellent sleeping

This bag was a perfect fit for my 6in twin trifold mattress. It is roomy enough for the sheets and mattress protector. It was easy to put the mattress in the bag.The wheels seem sturdy and make it easy to move the mattress.

I purchased the Inofia 6" Memory Foam Tri-fold Mattress for a twin XL bed frame, $195.34. I could not be more pleased!! I also bought a zippered cover for storage -- Cuddly Nest Folding Mattress Storage Bag with Wheels & Handles, $34.99 for Twin XL -- which is very high quality and fits the folded mattress perfectly. Additionally, I purchased the Amazon Basics Foldable Metal Platform Bed Frame, Twin XL for $108.55. The ensemble total cost was foughly $350. A far cry from the Murphy beds I priced in the $2000+ category. This combination is phenomenal. I am proud to roll it out for the occasion overnight guest. If I entertain a couple, I will give them my queen bed and I will happily sleep on this ensemble, myself. The ensemble fits into my hobby room closet, which is only 22 inches wide (mattress is 18", folded, and frame takes up another 2", folded). There is no chemical smell to the mattress -- no smell at all that I can detect. It is very comfortable (medium/firm), and took about an hour to fully expand from its compressed delivered state. I highly recommend all three items.

Fits perfect, even for my thick thick folding mattress beds. No smell. Easy to put away when not in use. Really heavy duty. See through plastic is great to see which bed is in the case. Wheels are great. Stitches are good and strong. Handles are not falling apart. Zipper does not snag or break. I bought folding mattresses as an investment for guests to sleep on and I am happy I went a little extra when deciding to buy this storage bag. Had a small leak in the basement and had wet floors; the storage case was wet on the outside but on the inside it was dry along with the bed.

Overall this mattress bag is exactly what I was looking for. It's sturdy, has sturdy handles on two sides, and the wheels make it easy to move around. I bought a twin size for my twin trifold mattress, but it's a tight fit and a bit tricky to get the mattress into it as it unzips only part way. Once in, there's no room to spare. I sleep on my mattress nightly and then store it in the bag during the day, so I wish it were a bit easier to put into the bag. Otherwise, it's a very good storage bag and would be perfect for travel.

I really like my folding mattress storage bag! I was easy to assemble because there's REALLY NOTHING TO ASSEMLE. I just unzipped it and stuffed my trifold mattress in there. It's a bit on the large side because my mattress is smaller than a twin-sized mattress. It has adjustable clips to tighten at the top and that actually made it easier for me to fit in my little car. The other thing I like are the wheels on one side of the bag! I don't have to carry it around when I can pull on one end and roll it on the wheels. Very practical & comfortable to pull. It has a good quality zipper. I had also ordered another mattress and the bag was included. When I tried to stuff the mattress inside the bag, the zipper broke-cheaply made. This carrying bag feels like canvas, but it's not. Well made.
