Tomorrow Sleep and Lull both sell memory foam mattresses. The main differences between the companies are that Tomorrow Sleep incorporates springs and offers two firmness options, while Lull offers only one all-foam mattress model. This review will compare similarities and differences so you can decide which is the better choice for you.
- Mattresses from both companies are 10” thick.
- All options are constructed to ensure you sleep cool.
- Options are similarly priced. ($550-$1,150 for Tomorrow Sleep, $550 – $950 for Lull)
- Both companies incorporate memory foam.
- Both companies offer 100-night trials.
- Both companies offer free shipping.
- Tomorrow Sleep has a more complex construction.
- Tomorrow Sleep has springs and side rail system to reinforce edge support.
- Tomorrow Sleep has a Medium Soft and Medium Firm version, while Lull offers only one firmness level.
- Lull is a bit firmer than the Tomorrow Sleep Medium Firm
- Lull incorporates materials into its memory foam top layer to draw heat away from the body.
Tomorrow Sleep Construction
- Both versions of Tomorrow Sleep differ mainly in the thickness of certain layers, but otherwise are similar in construction.
- The cover is made of polyester and nylon.
- On top is a 1-inch layer of memory foam with phase change material, which gives the mattress its memory foam feel.
- The next layer is gel foam, providing comfort and bounce. In the Medium Soft option, this layer is thicker.
- The Medium Firm option additionally has a layer of memory foam-like “dynamic response foam.”
- Both Medium Firm and Medium Soft have a 6-inch support layer consisting of individually pocketed coils. However, in the Medium Firm option, the coils are thicker
- A foam side rail system reinforces edge support.
- A 1-inch layer of stabilizing foam forms the base in both options.
- Lull has only three layers.
- On top is 1.5 inches of gel-infused viscoelastic memory foam, which draws heat away from the body to prevent hot sleeping.
- In the middle is 1.5 inches of latex-like foam, which gives the mattress some bounce.
- The base layer is 7 inches of core polyurethane foam.
- Tomorrow Sleep has more layers.
- Tomorrow Sleep incorporates springs.
- While both mattresses incorporate memory foam, Tomorrow Sleep has more of a traditional memory foam feel.
- Lull is firmer than both Tomorrow Sleep versions.
- Lull has a simpler construction.
- Tomorrow Sleep sleeps cool on account of its incorporation of springs.
- Lull uses gel in its memory foam to ensure cool sleeping.
Lull is firmer and has more bounce than both options from Tomorrow Sleep, and returns to shape more quickly. Tomorrow Sleep is softer and and has more of a quicksand feel. The Tomorrow Sleep video is for the Medium Firm option; the Medium Soft version will be even softer.
Motion Transfer Differences
Despite being firm and springy, Lull isolates motion well. Tomorrow Sleep’s mattresses also keep motion from transferring, but thatis less surprising because Tomorrow Sleep is so soft and quicksand-y. All options are good options for couples.
Pick Tomorrow Sleep If:
- You want a longer-lasting mattress– Mattresses with springs are more durable than all-foam options, in most cases.
- You’re a fan of memory foam– Tomorrow Sleep will give you more of a true memory foam feel.
Pick Lull If:
- You want faster recovery– Lull has a nice foam feel, but springs back into shape more quickly than Tomorrow Sleep.
- You sleep on your stomach or back– Lull is a bit firmer than Tomorrow Sleep’s firmer option, making it a better option in most cases for stomach and back sleepers.
Even when two mattresses both have memory foam top layers, they can feel very different. Hopefully this review was helpful in helping you compare options. Please share any specific questions you have in the comments.
