- The 4 bands for turning the mattress are for the ass ... ;-) work should save the manufacturer.
The weight of the mattress is too high for the seams. Bands are unnecessary.
CONCLUSION: Highly Recommended for the budget conscious and yet a good quality!
That's it .... hope I could offer you a helpful review.
