    • Extremely Happy.
Style: 10'' Original Lull Size: Queen
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. ... show more

    • The Perfect Firm Mattress!
Style: 10'' Original Lull Size: Queen
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. ... show more

    • A solid mattress
Style: 10'' Original Lull Size: King
It's a very decent, comfortable memory foam mattress, not notably better or worse than others in this price range. Been sleeping on it quite comfortably now for several weeks, no real complaints.

    • Fall asleep faster, more comfortably, and drier.
Style: 10'' Original Lull Size: California King
I started with a 4 star but changed my review to 5. I have only ever owned spring mattresses and had my last one too long. My back issues disappeared. I stopped sleeping hot. Is it weird to like the perfectly square corners? It just looks nice even with sheets and covers on it. Negatives are it’s heavy but it’s a California king so whatever. The airing out / up was a little funny but no issues and it filled out quickly. We slept on it on the floor but after some reading found it recommends it doesn’t dry very well unless you lift it off the floor on a platform/box or put it on its side when not using it. ... show more

    • LOVE! LOVE! LOVE!!!
Style: 10'' Original Lull Size: King
This is literally the most comfortable bed I have ever slept in!! So comfortable that we are going to get each of our girls one when they graduate from college!! We bought the King and I am so glad we did!! Our dogs love it so much they don't even get up in the middle of the night to go to the bathroom! They don't even want to get up in the morning! Also, when my dog sleeps, she runs in her sleep, and my husband twitches, and I don't even notice! I am getting the BEST sleep I have ever gotten!! I wish we would have purchased this bed years ago!!! ... show more

    • Best Mattress Purchase Ever
Style: 10'' Original Lull Size: Queen
As a 54 year old man I have been through several mattresses in my life. I bought this mattress in February 2017 to replace and old innerspring. I did quite a bit of research and since it got a good ratings including on Consumer Reports I pulled the trigger and bought it. At first it seemed way too firm and, as a side sleeper, I was waking up with minor shoulder pain. After about two weeks I got used to the mattress and it has been great ever since. I fall asleep faster, don't wake up near as much during the night and sleep much more soundly. If I do wake up at night I fall asleep much faster than before, I used to wake up with one arm being numb and that never happens now. I even dream better. This is a terrific mattress and I'll never go back to an innerspring. I bought a second mattress for my son and he agrees, this is a great mattress. ... show more

    • Didn’t work for us but Lull Stood behind their 100 Night Trial
Style: 10'' Original Lull Size: Queen
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. ... show more
