Vibe Gel Memory Foam 12" Mattress, TwinXL

Ordered two matching twin XL mattresses for king adjustable base. Received two different mattresses although SKU are the same. One acceptable made in Spain; one unacceptable made in Phillipines. Arrived from Amazon in same shipment in identical boxes. Both were left to fully expand four days. The one from Spain is the only one that matched the description in foam layers and expanded to 11 inches. The second one from Philippines has half the layers of foam, expanded to 8 inches, and is one sided with a hard side like cardboard platform mattress. It is in the mattress cover backward. It collapses to two inches when pressure is applied and looks like a kid wearing his dad's jacket. I have to return both since they must match to fill a king size bed base. I can't take the chance on purchasing one that may or may not match the Spain one. Really a pain to try to return a mattress when the only option is UPS drop off. Impossible to get back in the box. It's the chance you take when purchasing online in a box. If I had received two of the same one from Spain, it would have been a very nice mattress solution. They were on sale and a good deal. Now it cost almost $100 more per mattress. I didn't think purchasing two identical mattresses at the same time would end in this headache. My bad.
