4 stars for the excellent after sales service and overall quality of the product. The packaging and build quality is excellent.The mattress itself did not work well for me, if you’re looking for good support and are around or above 170 lbs, 5inch memory foam will probably not support you like a regular multi layered mattress would.Having said that, everyone has different definitions of comfort, my wife found the mattress good.I was impressed by the commitment of the after sales and the brand to ensure I’m satisfied with the purchase. I reached out to them with my concerns and as per the 100 night trial they offered me a fair partial refund to make it up to me.Overall I think this is a good option for guest or camping mattress. I had a good buying experience so I trust this brand for any future purchase.I enjoy the versatility this mattress gives. I fold it up and keep it in a corner with a blanket and pillows as a lounger when I don’t have guests. Then, unfold and make the bed in minutes when someone needs a place to sleep. This mattress is good for people who enjoy a firmer mattress yet still comfortable. It also works well with adjustable bed frames.This was such a great purchase. I bought it to use for camping, but it has ended up being used for sleepovers and been brought on vacation for an extra bed. It is just so comfortable. I also like the fact that the places that you fold the three pieces together do not spread when you are sleeping and the bottom has little bumps on it to grip the bottom of my tent.A twin sheet set covers perfectly. The only draw back is that it did not come with a carrying case. I purchased that separately.Sleeps so well !!! And folds up to get it out of the way !! We put this in our cargo trailer to sleep and has been awesome so far !! Totally worth the money!!Hmmm. Comfortable but the folds want to separate. No instructions so not sure what is the top and what is the bottom. No case for storage!I ordered two of them for my grandsons to use during a large family gathering at my house. They looked at them suspiciously, but when they tried them out, they were yelling. “I’m sleeping here! I’m sleeping here!” They loved them. I bought 4 flat sheets to make covers for them. Kids never seem to use top sheets, so just a light blanket and a pillow was needed for each. The kids slept extremely well. I had also wanted to use them in the back of our minivan too, but each one was a twin size. I wasn’t too bright when I thought I could get a king size mattress back there. We will probably take one with us when we travel though. I tried to store them under two of our beds, but they wouldn’t fit. All in all, great purchase!!Came fast and as ordered in a box that looked to small for a mattress. Unpacked it and it grew to the full mattress in about 24 hrs. Looks very good in my van. Very nice material, looks very sturdy, can't wait to camp with it as soon as it gets cooler.This mattress is so comfy! Very thick but folds up easily and is easy to lift! Worth every penny!
