I could not be more happy with my memory foam bag chair! It is not shy of the memory foam pieces either! It bounces back to same puffiness as if it were never used. The zippered cover is very high quality,  soft yet strong, and amazingly easy to put on and take off! Best part of the cover is, I washed & dried it, and it did not shrink one tiny bit! We are going to be purchasing 4 more! I also need to mention I've had 2 back surgeries and still have horrible sciatica, and this has been a miracle for me!
