Love Lull foam mattress. 1st time we’ve slept on foam and it’s incredibly comfortable. We have also purchased the King size mattress. Great quality and price. Would highly recommend.

This is my 2nd Lull mattress, I had to pass my first one on to my son because he loved it so much! I’m forever a lull mattress fan! I sleep like a baby on this and it seems to help with my back pain. It’s not too soft and not too firm. Best mattress I’ve ever owned. I will never buy any other brand.

My second Lull mattress. My first one was 10 years old. It still was not in to bad of a shape. (It is being used as a cushion on a homemade bench!) I bought the same Lull again. The 10 inch. Love it! It is as perfect as the first one. No smell at all. Not to soft and not to hard. Just right!

Well I am going to start off by saying this mattress just wasn’t for us. I was able to sleep on it but woke up with neck pain. My significant other though was not able to sleep at all on it. She complained of it being too hot. So we sent it back after 4-5 weeks of receiving it. We tried to make it work for us but we just couldn’t. I still give this a 4 star review; why? Because overall the experience was good and I don’t think it’s fair to blame the company for US not finding it comfortable. After all mattresses are not a one size fits all type of thing! We ordered the matress through amazon, it came, we unboxed it, allowed it a few hours to decompress. It fully decompressed all the way, was clean, no odor and really felt comfortable to initially lay on. Once we had made the decision to return it, we contacted Lull and they scheduled the pick up. Once the mattress was picked up and Lull verified it was picked up, we had our full refund within a day or two. Overall as easy as the process was of getting and even returning it with a full refund; I would recommend it to someone who might think it would work for them.

We had our last mattress about 11 years and I did a lot of research when it came time to replace it. I am used to a very hard mattress but my wife likes one somewhat softer. We considered the sleep number but found that the divider in the middle was just not something we wanted to deal with for several years to come. We looked at other traditional foam mattresses but could not justify paying the outrageous prices attached to some of them. Then we came across the Lull mattress and started to look into it. All of the reviews seemed to indicate that it was definitely on the firm side and people really seemed to love it. When you factor in the 100 night trial, free financing and quick low cost delivery (unless you buy through Amazon.... but that is another review) free return and 10 year warranty it is absolutely a 0 risk trial. We got it, set it up about 6 pm in the evening and slept on it that night. It definitely took 3 to 5 nights to get used to it but we both love this mattress. For the first time in years we can sleep on our backs as well as our sides and definitely sleep much better through the night. As someone who likes and is used to a hard mattress this is amazingly comfortable.

Set name: 10'' Original Lull
I'm 80 years old, and suffer with lower back problems. Based upon various online reviews, in 2019 I took a chance, and ordered a Lull mattress. It replaced an expensive - $3600 - memory foam one my wife and I had for 7 years, that had become uncomfortable. Now, three years later, we still couldn't be happier. The queen size Lull, at less than a third the price of the mattress it replaced, has proven more supportive, and to sleep cooler. Although it doesn't entirely eliminate any awareness of my wife's shifts in position, as did the previous mattress, they're barely noticeable. We spent a night sleeping in the guest bedroom, while waiting for the Lull to completely inflate before sleeping on it. Nevertheless, it was worth it. My wife and I both highly recommend this mattress.

This is firm - even for a medium plush. Thought it would be so much more soft than it is and it’s a lot of money, this brand, so If you’re not the type that likes or needs that, select the “plush” option or go with a different brand for your mattress. Packaging was great, arrive clean and packaged nicely. But, It’s almost worth it to spend an extra $150-$300 and get a purple, Casper, or tempurpedic that lasts and meets quality expectations.
