Great product.   I ordered twin xl mattresses for my twins who are 6'1 at 14 yrs old.  They arrived quickly and rolled up.  Be careful cutting the plastic off, so you don't cut the mattress. Also watch out as it springs open with force.  It was cool to see.  The mattress is very comfortable. The top is soft and cozy , but the mattress does have medium support. It has a slight smell, but it is not offensive.  My boys love them. I would highly recommend this product.  I also feel that the customer service associates are helpful and friendly. You can't beat free shipping.  Thanks Wayfair. (:  Susie Lawrenceville, NJ
