Lull Mattress Review – Great For Back Sleepers?

Lull is a bed-in-a-box retailer that offers an all-foam mattress for a value price. The Lull mattress incorporates three types of foam for a blend of comfort and support.

In my experience, this all mattress is medium in terms of firmness. This means it could be best for back sleepers and some combination sleepers.

Will you find comfort on this medium-firm mattress? Read on for my full review.

You Might Want To Pick The Lull If:

  • You Are A Light Or Medium Weight Combination Sleeper: If you sleep in numerous positions during the night and aren’t overly heavy, this could be a good fit for you. Being that this mattress is slightly firmer than average, it has a nice balanced feel that could give the proper support and comfort in a variety of sleeping positions.
  • You Are A Back Sleeper: Medium-firm mattresses are often a good match for back sleepers. This mattress should give you the proper support, while still allowing your hips to sink in slightly. Your spine should stay neutrally aligned on the Lull.
  • You Like A Foam Feel Without Feeling Stuck: You should get the pressure relief of a foam mattress while still being able to move around easily on the mattress. The soft top layer isn’t very thick, so you shouldn’t sink in too far.

You Might Not Want to Pick The Lull If:

  • You Are A Heavier Side Sleeper: You may press through the soft upper layers and engage the support layers beneath. Because of this, you may find this mattress to be too firm, especially if you sleep on your side.
  • You Are A Heavier Stomach Sleeper: This mattress may not be firm enough for if you are larger and sleep in this position. You may require more overall support to ensure you don’t sink in too far at the hips.
  • You Prefer The Feeling Of An Innerspring Mattress: This is an all foam mattress, so you will get some of that slow compression that comes with memory foam. If you like the contouring and support of coils, this may not be the best match for you.

Construction Overview

  • The mattress is 10” tall.
  • First, there is a soft, thin cover. It is a premium blend of fabrics and is quite breathable.
  • Then, there is 1.5” of a gel memory foam. This is soft and made for pressure relief.
  • This is followed by 1.5” of a transition foam. This is there to transition you to the firmer support layers.
  • Finally, there is a 7” base support layer.
  • All the foam in the Lull is CertiPUR-US® Certified, so it is eco-friendly.
  • The Lull is Made in the USA.

Construction Takeaways

  • The Lull is available in Twin, Twin XL, Full, Queen, King, and California King.
  • The mattress works with an adjustable bed.
  • The gel foam is quite slow to respond. This means it should be good for pressure relief.
  • At the same time, the soft gel foam layer is not very thick. Because of this, you shouldn’t sink in too much. You should be able to move around on the mattress without feeling “stuck.”
  • Also, the transition layer has some bounce to it, which also keeps you from getting “stuck.”
  • The top foam layer is injected with a gel polymer, designed to dissipate heat. This foam is also open-celled, meaning it allows for airflow. Overall, you shouldn’t be sleeping hot.
  • Because the gel foam layer is so thin, heavier people may press through it and engage the support layers beneath. The mattress may seem firmer to larger side sleepers. According to the company, the Lull can support two people weighing up to 250 lbs. each. If you are close to or above the 250 lb. range, I would recommend looking at getting a mattress specifically created for heavier people.

Firmness and Feel

For me, the mattress felt like a 7/10, just a little firmer than average. The top layer is very soft and slow to react, but it also only 1.5”. The next layer of bouncy transition foam ensured I didn’t sink in too far. Because of this, I felt nice pressure relief without sinking in too far and getting “stuck.”

On my back, I felt my hips sink in slightly, but I still felt nice overall support. On my stomach, I also felt the proper amount of support. On my side, I experienced nice pressure relief, but I did feel a bit of those firmer layers beneath.

If you are a heavier person, you may find this mattress to be firmer than I did, as you press through the soft upper layers down to the firmer transition and support layers. At the same, this mattress may be too soft if you are heavier and sleep on your stomach.

In terms of feel, you have a thin layer of memory foam on top, so you have a little bit of that soft, foam feel. However, together with the firm layers beneath, the mattress has a balanced feel overall.

Motion Isolation

Being that it is an all foam mattress, I expected the Lull to perform well with motion isolation.

There was barely any motion transfer during my tests. If you sleep with a partner, you shouldn’t feel them moving around. This could be a good match for couples.

Edge Support

Memory foam mattresses often collapse when you sit near the edge. However, while there was some compression, I still thought the Lull had good edge support.

Sitting on the edge, I didn’t feel like I was going to fall off. Likewise, lying down, I didn’t feel like I was going to be ejected from the mattress. This also makes it a good pick for couples.

You can see the nice edge support in the photo below.

Marten’s Take

Marten is a staff writer for us. He has a much different body type from me. He is 6’7″ and weighs about 230 lbs (I am 5’9″ and 160 lbs.). Here is what he thought about the mattress.

Joe felt it was close to a 7 for firmness. For me, it was closer to an 8.

On my side, I definitely press through the top layers down to the support layers underneath. I felt a little bit of pressure on my shoulders and my hips.

On my stomach, I needed more support overall. I was bowing in. On my back, this is where the mattress really worked for me. On my back, I felt good support overall along with nice comfort.

If you are a back sleeper and you are my size, this might be a good choice for you.

Marten’s experience fits with my thoughts on the mattress. He is heavier, so he has some issues on his stomach and side. However, it did work well for him when he was on his back. This matttress could definitely be a good choice for back sleepers of many sizes. 

What Makes This Mattress Stand Out?

  • This mattress gives good pressure relief without you feeling stuck. While the top layer is very soft, the transition layer keeps you from sinking in too far. The Lull feels comfortable, but it is still easy to move around on the mattress.
  • The Lull is great for medium and lighter weight combination sleepers. If you sleep in a variety of positions during the night and you aren’t overly heavy, this mattress should give the proper support and comfort.
  • Its medium firmness makes it a good match for back sleepers of many sizes. Whether you are lighter or heavier, you should find comfort if you sleep on your back.
  • The open-celled foam promotes airflow and cooling. Together with the breathable cover, this should keep you from sleeping too hot.

The Lull mattress is one of my preferred bed-in-a-box models, especially at this price range. It offers great support, and is one of the few mattresses I recommend for people that sleep in multiple positions throughout the night. Overall a good option.

How To Unbox This Mattress

The Lull is a bed in a box mattress, which means it will come compressed and be shipped straight to you. You will want to begin by removing the rolled up Lull mattress from its box. Then, preferably with another person’s assistance, position the roll on your bed.

Carefully cut the away the first layers of plastic until the still-compact mattress can be laid down flat. Then, pierce through the final layer of plastic and the Lull will expand. Simply clear away the excess plastic and allow your mattress to breathe and fully expand.


This medium-firm mattress could be a great match for back sleepers of many sizes. In addition, lighter and medium-size sleepers should find comfort and support in numerous positions.

Heavier side and stomach sleepers may require more support in those positions and may wish to seek a firmer mattress.

The Lull comes with a 100 Night Risk-Free Trial and 10 Year Warranty. Financing is available along with free shipping.

  1. I have had mine since April, a big crater on my husband’s. it’s horrible. Please, people, don’t buy the mattress. Lull would not refund my money, liers, liers…… bet this won’t get posted

  2. Joe,

    With so many mattress choices it is difficult if not frustrating when making a decision. while a mattress is a personal decision, for me it is one that has already been proven to be life changing.

    I have spinal issues and have had surgery on my l5/s1 disks to correct, but continued to have pain. My wife and I attended a home show were a bed company Rims was showing their foam mattress adjustable bed and after looking at it we decided to purchase thinking it would help.

    To my dismay, instead of helping with my back, the mattress has caused me to have severe hip and shoulder pain. I’ve been diagnosed with bursitis, treated with men’s, therapy, injections, needles you name it without helping the problem created by this mattress.

    After a year on this mattress and working with RIMS with no positive relief, I purchased a stearns pillow top. For the first 8-10 months it helped, but now I am once again in severe pain in my hip and both shoulders.

    I need to find a mattress that will help, I am suffering.

  3. I’m bedbound and suffer from severe chronic pain. Do you think this would be a good mattress for someone who is in the bed 90% of the time?

  4. Hi
    I have seen a few comments from others saying that you can’t use box springs with these mattresses otherwise it will cause soft spots???? They recommended bunkeeboard or a solid piece of wood. Any thoughts?

  5. I’m thinking of replacing an aging inner-spring mattress with a memory foam design like you described. I’d like to know how long the Lull mattress is expected to last with proper care.



  6. My husband says he has a tough time sleeping because he gets hot. Does this mattress really keep you cool through the night?

    • Hi Jean – they’re pretty similar, biggest difference would be the feel (check out my feel videos in each review for the difference). Bear also has some recovery-specific material that interests some shoppers.

  7. What about edge support? Is it suitable for sitting on the edge to put your shoes on? Or does it sink too much?

    • Hi Shelly – the Lull actually has “latex-like” foam, not actual latex. Not sure how that would effect your allergy, I would speak to them directly with those concerns.

  8. After reading reviews, I am torn between the Lull mattress and the Loom & Leaf mattress. I sleep “hot” – otherwise really like the feel of memory foam. I also have a pet peeve about mattresses that lean down toward the sides. Any thoughts? Thanks in advance – so appreciate your reviews!

  9. What about Off Gassing? Need a new mattress for my 18wheeler and would like to try a memoryfoam but don’t want the smell.

  10. question: i have bursitis in my left hip/leg and have woken up in horrid pain on several occasions. would the Lull mattress be a good choice? We bought the Serta 2 years ago with high hopes and it’s not doing it. Also have had back issues for life and would like something where i am not in pain when i wake up. thanks

  11. If you were recommending a mattress with a firm bounce that would be used solely for amorous activities what would it be?

  12. I just received a consumer report (74 mattresses tested) IKEA at $550.00 received the highest rating in memory foam section. and I did not see Lull listed. I wonder why. It’s on pages 27 thru 29 of feb 2017, titled ” secrets to a great nights SLEEP”

  13. About a year ago we bought a Beautyrest Pillow Top mattress.
    After a few months both of us developed back pain and sciatica.
    I’m considering a Lull.
    Lately, I’ve been sleeping on a Futon on the floor, and my back pain is reduced, but not gone.


  14. Hi,Joe. I’ve had 3 back surgeries ND degenerative arthritis of the spine. I have chronic pain..And I was wondering f lull mattress would help my pain. I really think my mattress adds more pain. Thank U

    • Hi Debbie – I get this question a lot, and while I don’t think certain mattresses “target” pain, a good mattress that supports you well and keeps you aligned will definitely help with pain.

  15. I’ve had a Tempur-pedicure mattress for 10 years which I loved. I was hoping to get a less expensive mattress. We are trying out a Relaxed firm Loam & Loft it is too firm for us. Which mattress is the closest to a classic Temper-pedic feeling ? Thank you !

  16. We have a traditional (20+ year old) California King waterbed frame that we put a conventional box spring & mattress in (it has 6 drawer on each side and cupboard space in between). Unfortunately, there’s a lip on the footboard that goes over the end of the mattress (making it VERY difficult to change sheets, etc.) Can the Luff mattress be ordered by an odd size (i.e., shorter than the average CalKing)?

    • There is a smell to almost all of the bed-in-a-box options initially (Lull is no exception), but I found the smell to be gone within 48 hours. Any readers have a different experience?

  17. We currently have an older Sleep Number Bed and usually keep the firmness around 40-45. We are not as happy with it as we were the first couple of years. We have back and shoulder issues. Do you think the Lull Mattress would suit us?

  18. We are on I think our third mattress, and still no luck. First Dream Foam, didn’t work at all. Then we have tried Tuft and Needle – comfortable but woke up with horrible back pain. We are now trying Helix. Still having back issues but did like the ability to ‘build’ a mattress.

    We are using twin XL’s for a King size bed.

    Should we just give up on foam and go back to innerspring? Any advice I would appreciate it.

    Thank you,
    John G.

  19. hi,
    Any suggestions for online mattresses that delivery to Canada? We are side sleepers and my husband has a shoulder injury.

    Many thanks!

  20. Is there a box spring you would recommend to go with the mattress? I would want one so that the bed would be a little bit higher that it would with only a mattress.

  21. can you use the mattress on traditional beds or is it too heavy? I noticed it was placed on a very sturdy looking bed with no box spring.
