Comparing Construction (Materials & Quality)
Casper is rolled into a box and mailed to your house.
The entire construction stands 11 inches and is wrapped in a durable polyester fabric cover that is also removable.
- The top layer has a springy and responsive foam that delivers a bit of surface bounce and airflow that maintains the surface temperature of the structure.
- The third layer transitions between the soft and firmer layers with the company’s proprietary Zoned Support™, which is firmer under the sleeper’s hips so that the body rests level while still providing softer pressure relief for shoulders and lower extremities.
- The base layer is made out of dense poly foam that builds the foundation and gives spine-aligning assistance.
Lull is another bed-in-a-box that stands 10 inches tall.
The cover fabric is a soft and stretchable rayon and polyester blend that is breathable and should feel cool to the touch.
- The top layer contains memory foam that’s infused with gel to help keep the surface from overheating. This 1.5-inch layer molds to your shape and eases the pressure that can build up in your joints.
- The second layer helps the mattress transition from softer to firmer with a poly foam that is 1.5 inches thick that delivers support and motion isolation.
- The base layer’s 7-inch block of high-density poly foam was designed to hold your spine straight and comfortable while providing a durable foundation for the bed.
Comparing Firmness (Support & Comfort)
These mattresses share a lot of similarities in that they are all-foam constructions and both score around a 6 for firmness, using our scale that measures 1 to 10 or softest to firmest. Mattresses within the Medium scoring range are usually good for most sleeping positions and body types.
Casper is a brand that aims for a universal feel, and their newly updated third layer that bolsters the center of the construction and expands the brand’s versatility even more. Back and stomach sleepers sometimes need assistance in this area keeping their heavier hips level with the rest of their body to maintain a good sleeping posture. Side sleepers need good hip support while still allowing their shoulders to sink into the mattress and receive pressure relief.
The surface of Lull is a bit slower to respond than Casper, which provides a bit more surface contouring while the thicker base provides good spinal alignment for back, side, and stomach sleepers. The overall experience of the mattress is slightly quicker to respond due to the thicker and denser base and transition layers, and it is also a bed that offers good versatility.
Though both brands can accommodate a variety of body shapes, Casper might have a bit of an advantage with side and back sleepers who carry extra weight in their midsections and this is because of that Zoned Support™ system. Lull’s established weight limit is 250 pounds, and if you are substantially heavier, that is something to keep in mind.
Both combat heat retention but with different methods. Casper uses more breathable materials on the surface of their mattress while Lull infuses their memory materials with a bit of gel to wick away heat.
Comparing Sinkage and Bounce
We would characterize the sinkage in both of these mattresses as a gentle cradle, meaning your body will rest more on top of it than deep inside it, as can be the case with some competing memory products. Surface-level sleeping helps with temperature regulation because it brings your body into contact with circulating airflow.
Both brands delivery some bounce but from different sources. Casper’s bounce is mostly located on its surface while Lull’s bounce is more mid-level. This feature in both can work with the quicker-responding layers in each to aid repositioning.
Comparing Motion Transfer
Motion isolation is exceptional in both choices because of the combination of memory products and dense bases that do not conduct vibration and tend to muffle it at its source. People who are easily disturbed by their partner or pets getting in and out of the bed will enjoy both mattress’ limited motion transfer.
Comparing Edge Support
Both beds are compressed and mailed in smaller boxes, and brands in this category—especially all-foam choices—do not stand out with this feature. That said, both choices perform a bit better than average with this feature due to good foundational materials.
When seated on the edge of either brand, you may notice that your weight sinks a bit. However, you should not have a problem sleeping close to the side and your weight should feel secure even lying closer to the edge, an important consideration for couples who share their sleep space and use more of its surface.

Should I Buy Casper or Lull?
These two choices have a lot in common with only slight differences that distinguish the two. We think both have their own advantages, but it is up to you to decide which features are most important for you.
We Would Recommend Buying Casper if You are Looking for:
- Enhanced versatility. Casper’s build is designed for maximum versatility, which has only been strengthened by its newest updates that improve the sleep comfort of a population of back and stomach sleepers.
- Targeted spine alignment. The addition of Zoned Support helps out more stomach and back sleepers who require additional firmness in this area while providing extra pressure relief for side sleepers’ shoulders.
- Edge support. Casper’s performance in this category goes beyond what is typically expected from all-foam bed-in-a-box options and provides secure and significant support across the entire surface of the mattress.
We Would Recommend Buying Lull if You are Looking for:
- Want a more traditional feel. By layering the memory materials of this bed on the top, you come into contact and interact with more of the slow-responding and sinking feeling we often associate with memory beds. However, gel and cushioning depth should prevent you from overheating.
- More budget-friendly. This brand is priced about a 100 to 150 dollars lower than its competitor.
- Edge support. Lull ties with Casper with its surprisingly supportive edges that are made possible by its thick layer of dense base foam and transitional layer that surpass what is expected from bed-in-a-box brands.
That wraps it up. Do you want the enhanced and newly updated support system of Casper or would you rather experience the surface level sink in the slightly more affordable Lull?
Like we said, it is a tough call. If you still need some additional details, you can find them in our in-depth reviews of both brands that are available on our website.
