Lull Mattress Review – Great For Back Sleepers?

We receive free products to review and participate in affiliate programs. See our disclosure page for more information.

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, which means it could be an excellent option for back sleepers and some combination sleepers.  This review will go over everything people need to know about this mattress, including a full breakdown of the construction, the pros and cons, breathability, durability, support, comfort, edge support, motion isolation, and so much more.

Who Might Want To Pick The Lull:

  • Light Or Medium Weight Combination Sleepers: 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.
  • Back Sleepers: 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.
  • People Who 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 and switch positions. The soft top layer isn’t very thick, so you shouldn’t sink in too far.

Who Might Not Want to Pick The Lull:

  • Heavier Side Sleepers: 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.
  • Heavier Stomach Sleepers: 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.
  • Those Who 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 and features a simplified construction with three foam layers.
  • First, there is a soft, thin cover that is a premium blend of fabrics and is quite breathable.
  • Then, there is 1.5” of a gel memory foam, which is soft and made for pressure relief and body contouring.
  • This is followed by 1.5” of a transition foam, which is there to transition you to the firmer support layers.
  • Finally, there is a 7” base support layer, which is a fairly standard base layer in the industry.
  • All the foam in the Lull is CertiPUR-US® Certified, so it is eco-friendly and free from harmful chemicals.

Construction Takeaways

  • The Lull is available in Twin, Twin XL, Full, Queen, King, and California King, basically any size a consumer could want.
  • The mattress works with an adjustable bed or really any flat surface.
  • The gel foam is quite slow to respond, which means it should be good for pressure relief.
  • At the same time, the soft gel foam layer is not very thick, so people shouldn’t sink in too much. People should be able to move around on the mattress without feeling “stuck” and also switch positions.
  • Also, the transition layer has some bounce to it, which also keeps people 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, so overall people 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 as a result. According to the company, the Lull can support two people weighing up to 250 lbs. each. If people are close to or above the 250 lb. range, I would recommend looking at getting a mattress specifically created for heavier people.

Firmness and FeelLull mattress firmness rating

For me, the mattress felt like a 7/10, just a little firmer than average compared to other mattresses reviewed on this website. The top layer is very soft and slow to react, but it also only merely 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 and body contouring. On my stomach, I also felt the proper amount of support and firmness. On my side, I experienced nice pressure relief, but I did feel a bit of those firmer layers beneath.

If someone is a heavier person, they may find this mattress to be firmer than I did, as they might press through the soft upper layers down to the firmer transition and support layers. At the same, this mattress may be too soft if someone is heavier and sleeps on their 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 that contains memory foam in the top layer, I expected the Lull to perform well with motion isolation.

There was barely any motion transfer during my tests, so if someone sleeps with a partner, they shouldn’t feel them moving around. This could be a good match for couples who don’t want to be disturbed by their partner’s movements.

Edge Support

Memory foam mattresses often collapse when people sit near the edge. However, while there was some compression, I still thought the Lull had good edge support, perhaps because of how firm its.

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 as a result.

Marten’s Take

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

Joe felt it was close to a 7 for firmness, but 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, as I was bowing in at the hips. 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 someone is a back sleeper and they are my size, this might be a good choice for them.

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.

Summary
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 the shopper’s door. People will want to begin by removing the rolled up Lull mattress from its box, and then preferably with another person’s assistance, they should position the roll on their bed.

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

Overall

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, and financing is also available along with free shipping.

Consumers should take a look through this review multiple times, assess their own needs and preferences, and then make a more informed decision.
