We ordered the split king Flex with the adjustable base, plus the pillows, sheets, waterproof cover, and 6” legs for the base. Received most of the products rather quickly. It was easy to put together and although I initially thought the mattress might be too firm, it was perfect for us. It is firm but also well cushioned. Had a couple of minor issues but everyone in customer service I encountered was excellent. This company makes a great product, stands behind it, and provides quality support. Thank you!
