I purchased two of these 12” mattresses while they were on sale! I have always purchased Simmons Beauty Rest mattresses as I have dealt with a very painful back, spinal stenosis and that list goes on! I’m so dang impressed for my own quality of sleep with this mattress that cost less that half the price of what I’ve paid for my last two Simmons mattresses since 2014. I love the hybrid and I feel nice and cool sleeping on this. I always use my favorite cotton bed pad for comfort and as much cotton linen bedding for the most cool sleeping.
