Tencel related bedding stuff = Undisputed. Can't go wrong with them. Smooth, comfy, and moisture-wicking, dries fast too. And it is not as warm as cotton!
Memory foam related topper/mattress = Comfy, conforming, the right amount of cushion distributed to various parts of the body. And different specific levels of hardness specific to preference!
Service/Delivery = Top notch! Replies fast, and the delivery is within days. Won't be left feeling hanging the air waiting for response and replies.
