Need Help Deciding?
For most sleepers, we recommend the Big Fig Mattress over the Casper The One. It scores higher in cooling, edge support, durability and delivers stronger overall value. The Casper The One is the better choice only if budget is paramount — it saves roughly $600.
Big Fig Mattress vs Casper The One: What Actually Differs
The Big Fig Mattress is a hybrid build, while the Casper The One is a memory foam — that single difference drives most of the cooling, motion, and feel decisions below. The Big Fig Mattress stands 13" tall versus 11" for the Casper The One — a 2.0" gap that matters if you need deep-pocket sheets or are pairing with an adjustable base. Both sit at roughly 7/10 on the firmness scale — a medium-firm feel — so neither one is the answer if you need a dramatically different support level. The single largest performance gap is in cooling: the Big Fig Mattress rates noticeably higher than the Casper The One, which is the deciding factor if that dimension is high on your list. On a Queen, the Casper The One runs $799 versus $1,399 for the Big Fig Mattress — roughly $600 (43%) less, which is enough to factor into the decision unless the pricier model wins clearly on the specs you care about.
Which Is Better For Your Sleep Style?
Both rate the same for pressure relief — choose on firmness instead (side sleepers usually prefer the softer of the two: Casper The One at 6.5/10).
Firmness of 6.5/10 is closer to the medium-firm sweet spot back sleepers need for lumbar support (vs 7/10).
Firmer at 7/10 vs 6.5/10 — stomach sleepers need the extra support to keep the pelvis from sinking and arching the lower back.
Stronger cooling rating, which matters most for sleepers who run hot or live in warm climates.
better long-term durability and stronger perimeter / edge support — the two specs heavier sleepers should weight most.
Softer at 6.5/10 vs 7/10 — lighter sleepers compress less, so they typically need the softer of two options to get proper contouring.
Higher motion-isolation rating, which means less disturbance when a partner moves or gets out of bed.
