As such, the construction and feel of these beds is quite different. The Novaform ComfortGrande is an all-foam mattress, while the Casper hybrid boasts the attributes of an innerspring mattress and memory foam bed all-in-one. The Casper comes in more sizes than the Novaform, whose queen-size and larger beds don’t typically fit the needs of solo-sleepers. The Serafina Pearl is less expensive than the Casper original, costing nearly $300 less for the queen-size bed. Compare Casper Original and Novaform Serafina Pearl Prices This also means that Serafina Pearl gives a deeper hugging sensation than the Casper, especially the soft and medium options. And with polyfoam rather than memory foam along the top layer, the Casper is easier to move around on. While both beds deliver exceptional pressure relief, the Casper provides superior spine alignment thanks to its zoned support foam. Thanks to 3 different firmness options, the Serafina Pearl also accommodates all sleep positions. Because it has a thicker, more supportive base and 6” of contouring foam, it’s better for heavy sleepers than the Casper mattress. Novaform ’s Serafina Pearl boasts a 3” gel memory foam comfort layer, 3” CustomWave transition foam, and 8” of supportive foam along the bottom layer. While the feel is one of a medium-firm mattress with a soft surface, added cushion at the shoulders and stability around the trunk means this mattress works well for every sleeping position. The Casper mattress has a 1.5” plush comfort layer made from polyfoam, 2” of 3-zoned support memory foam, and 7” of firm support foam. What sets them apart is the thickness of their comfort and transition layers along with the types of foam used. Both the original Casper mattress and the Novaform Serafina Pearl are 3-layer memory foam mattresses.
