Sleep Rating

Durability
Good

Durability appears to be good for the Lull Mattress; the expected lifespan is six years, which is on par with most memory foam beds.

Motion Isolation
Very Good

Lull mattresses feature two layers of memory foam that absorb and isolate motion transfer to a significant extent, according to owners.

Conforming
Good

Lull mattresses conform closely to sleeper’s figures and alleviate pressure points to a noticeable extent.

Sex
Fair

Like most memory foam mattresses, Lull models may not be responsive or bouncy enough for some couples. However, the mattress is better for sex than softer foam beds.

Temperature Neutrality
Good

The Lull Mattress may sleep warm for some, but its breathable cover and gel-infused top foam layer help the bed sleep cooler than many competing beds.

Off-gassing
Good

Some off-gassing is to be expected when the mattress is new, but odors from Lull models will usually dissipate within a few days.

Edge Support
Fair

Like many other memory foam models, Lull mattresses offer minimal edge support; premature sinkage is common at the edges where people tend to sit.

Noise
Excellent

Lull mattresses are virtually silent when bearing weight.

How is the Casper built?

The Casper features a mixed-foam comfort system with top and bottom polyfoam layers and a middle memory foam layer. These materials create a ‘Medium’ feel that offers close body conforming. A high-density polyfoam support core reinforces the bed and helps maintain an even, sag-free sleep surface.

At 9 1/2″ thick, the Casper’s profile is considered shorter than average. It is also much lighter than the average all-foam bed (71 pounds in a Queen size), making it easy to lift and rotate for most owners.

How is the Lull Mattress built?

The Lull Mattress has a 3″ comfort system with a top layer of gel memory foam and a second layer of transitional polyfoam. These layers create a ‘Medium Firm’ feel that provides some conforming, but not as much as the Casper and most other all-foam beds. It also contains a 7″ high-density foam base that provides great sleeper support.

The mattress measures 10″ thick, which is on par with the average bed profile. Like the Casper, the Lull Mattress is relatively light (74 pounds in a Queen size) and easy to lift and rotate as recommended.

Casper Sleeper Ratings

The Casper’s ‘Medium’ (5.5) firmness and low profile make the mattress most suitable for sleepers who weigh 230 pounds or less; heavier individuals may find the mattress is too soft and/or too short. The Casper also isolates motion transfer exceptionally well and produces no noise when bearing weight, making it a good option for couples who experience sleep disturbances due to noise or movement.

Lull Mattress Sleeper Ratings

The Lull Mattress has a ‘Medium Firm’ (6.5) feel that is optimal for sleepers who are considered average weight (130 to 230 pounds) or heavier than average (more than 230 pounds). It may be too firm for those weighing less than 130 pounds, or those who like mattresses that hug the body closely. The Lull Mattress also isolates motion fairly well and does not make any noise when bearing weight.
