Customer Reviews:
After sleeping for couple days on this bed, I have to say it’s been a GREAT buy! It is my first memory foam mattress, I never know it could be so comfortable to sleep on. My old spring mattress was firm and stiff which gave me occasional back pain in the morning. But with this one, I literally felt like sleeping on a cloud. The mattress has a good amount of cushioning for joints and pressure point, soft and supportive. | I was simply amazed by the compact size of carton when the mailman brought the package. Yes the mattress is all rolled up in the box. As instructed, I opened the box, took off the outer bag, then opened the inner plastic and wow…the mattress immediately expand itself to original size. I left it expand for 24 hours to get the right thickness. The cover is well constructed, looks like making from high quality material. | Overall, I am really satisfied with the purchase, I am considering to buy one more for my parents. Highly recommend it to everyone!
