First night and I had vivid dreams. Tells me I was deep in sleep! Why Because this bed is absolutely comfortable and amazing. My prior mattress was all Memory Foam. Was concerned this hybrid would be too firm. But took a chance because hybrids provide better lumbar support and edge support. Well, I’m glad I took the chance (thanks to reviews)!! You gently sink in (not too much, just the right amount) and it feels just as great as all memory foam bed. The support is great. The springs make it much easier to jump out of bed too. Highly recommended! BTW, Wayfair has the best price for a King Size anywhere!
