Lull and Zinus are two well-known names in the world of mattresses and many people find the Lull vs. Zinus choice interesting because both manufacturers offer a large number of features that can improve the quality of your sleep. Lull offers a single memory foam mattress in a box that has become somewhat of a cult mattress online in recent years, whereas Zinus has been producing mattresses since 1979. This means that they have the experience to craft high quality mattresses while also building their online customer experience. Unlike Lull, Zinus offers three types of mattresses lines, which include memory foam, coil, and gel memory foam varieties.
The Zinus vs. Lull comparison can help you in designing which mattress should be the next one on your bed. For this review, we compare the Lull mattress with one of the most popular and comfortable Zinus mattresses, the Gel-Infused ActivFRESH memory foam mattress, which is one of the company’s bestsellers.
Lull is a newer player on the mattresses market, and it offers a singular model of business that sees the company producing a single type of mattress made from memory foam. On the other hand, Zinus has been in the business for over 40 years, which means that they had the time to improve the construction of their mattresses, and this can be seen in the mattress we chose to review, the Gel-Infused ActivFRESH. While the Zinus mattress is more affordable, the Lull one comes with features that may be worth the higher price tag, depending on your sleep habits. Both mattresses are constructed from memory foam, with the Zinus one featuring a gel layer, but they vary in firmness, with the Lull mattress being a medium firm and the Zinus one a medium.

The Zinus Gel-Infused ActivFRESH is a memory foam mattress that offers good support and cool comfort for an improved quality of sleep. Also made from memory foam, the Lull mattress is constructed from multiple layers and designed for sleepers who prefer moderate firmness.
Both mattresses offer good sleeper comfort and spinal support, which are two of the most important factors to consider when choosing a mattress. The sleeping experience may differ according to the firmness you choose.
Firmness and support
If you are looking for a memory foam mattress that is a bit firmer that the average, choose the Lull mattress, which is a medium-firm model at 6.5. On the other hand, the Zinus Gel is a medium when it comes to firmness, and some users may find it too soft.
The Lull mattress is injected with a gel polymer in the top layer to transfer the heat from your body and disperse it. The open cell foam structure also increases the airflow. The Zinus mattress also offers you cool nights thanks to its cooling gel layer that will prevent you from overheating, even in the summer.
Many reviewers mention that the Lull mattress is great when it comes to the motion transfer feature, which means that you won’t feel every move your partner makes in their sleep. This is thanks to the top two layers of foam that dissipate most of the motion. The Zinus Gel-infused mattress has motion transfer capabilities well above what you would expect from a mattress with this price tag, but it doesn’t prevent motion transfer as well as the Lull.
The Lull mattress does not have an instantaneous response as you might expect, which means that the foam doesn’t bounce back into shape immediately after you apply pressure on it. The same goes for the Zinus, but the Lull is the winner in this category.
Resilience and bounce
Bounce and resilience are important for the general mattress comfort, and the Lull’s firmer feel offers a better amount of bounce when compared to the Zinus. It is less than what you might expect from a coil mattress, but still good for a memory foam one.
The edge support of the Lull is above average, thanks to the three layers of foam, which makes the mattress a good choice for those who like to sleep closer to the edge of the bed. The Zinus mattress gives you a bit of that roll-off feeling, as the edge-support is just average.
Inflation time, off-gassing and smell
The Zinus mattress requires 48 to 72 hours to expand completely, a time that the manufacturer mentions can be influenced by cold weather and other factors. On the other hand, the Lull mattress does most of the expanding in the first 2 to 5 hours and will expand fully after 24 to 48 hours. Both mattresses have a slight smell for the first days, but that will pass with off-gassing.

Both mattresses are very good choices for back sleepers, but they work well for other types of sleepers as well. Side sleepers would benefit more from the Lull mattress though, while light stomach sleepers may want to look at the Zinus first. Heavier stomach sleepers, on the other hand, should consider the Lull.

In the Lull vs. Zinus battle, the winner should be the mattress that best fulfils your personal needs. The choice should depend on what you have been looking for specifically for your sleeping style, and the priorities you have when it comes to healthy spine alignment. The budget is of course an important factor to take into account when choosing a new mattress, and if you are looking for a great budget-friendly model with all the bells and whistles provided by the higher price competition, Zinus should be your matters of choice. However, even though it is more expensive, the Lull mattress offers more in terms of quality and comfort while still remaining an affordable choice when compared to the vast majority of the mattresses available on the market.
