I looked at all the reviews about this bed. It delivered with no issues. One of my children is an engineer therefore bed was not a challenge to assemble. I ordered the full size bed. All the reviews are correct the full size bed frame is wide than a full mattress which causes extra space between the mattress and frame on the sides. This issue also causes the mattress to slide. The manufacturer should have made the frame so the mattress sits inside the rails to keep the mattress from sliding even if the frame is  wider. I purchased a full box spring and mattress set instead of the mattress only. 
Overall it’s a decent bed for a guest room some minor adjustments to the frame and you could have gotten 5 stars!!!!
