Hi psrv,
The Love Bed was changed to a different design around March 20th.
The previous version used 3" convoluted synthetic continuous pour Dunlop on top of a 7" 2 lb convoluted polyfoam. The cover was quilted with about 1" - 1.5" of polyfoam (depending on the firmness choice) for a total height of about 10" - 11". These are all high quality materials and there were no lower quality materials or weak links in the design and it was suitable for any weight range.
You can see more information about their current design in post #2 here in the simplified choice topic but to recap the new version uses 2" of hole punched 2.7 lb energex high performance polyfoam on top of 1" of a 1.8 lb polyfoam transition layer on top of a 6" 1.8 lb polyfoam support core. The cover is quilted with about 2" of 1.5 lb polyfoam for a total height of about 10" to 11". Energex has some of the properties and point elasticity of memory foam but is a more resilient material and doesn’t have the slow response and temperature sensitivity of memory foam so it would be a little bit less resilient than the latex that was in the previous version.
While some people may prefer the “feel” of the new design because of the difference in the feel and properties of the Energex (which is closer to memory foam than latex) … because of the thicker quilting layer and the 1" 1.8 lb polyfoam transition layer and the slightly lower density of the base layer this would be a less durable mattress than their previous design so while it would be suitable for those that are in more average weight ranges … I would add a caution for those that are in higher weight ranges (in the 200’s or higher) in terms of durability and the likely useful life of the mattress.
