We have had a nexgel bed for a month and we are sending it back. Worst decision we have made for such a large purchase. On top of the honey comb gel there is 2 inches is batting. We would wake up sweating during the night. We would also toss and turn all night waking up to a sore back. My wife only weighs 130 and I weigh 180 and felt like the gel bed was too firm. We were gone 2 weeks on vacation and my mother slept on it and said it was the worst mattress she had ever slept on. If you do buy one make sure you get the nexgel mattress from a dealer that offers a 30 day money back guarantee, not just a mattress exchange.
