Mattress firmness guide

What soft, medium, and firm actually mean across our mattress lineup.
Why firmness labels are unreliable
There is no industry standard for mattress firmness. One manufacturer's 'medium' is another's 'firm.' The label is a marketing shorthand for a feel that depends on your body weight, sleeping position, and what you're comparing the mattress to. The only way to know if a firmness works for you is to lie on it in the position you actually sleep in — not sit on the edge, not press with your hand, but lie on your side or back with your full weight. We keep every mattress we sell on a floor frame at the showroom for exactly this reason. If you're ordering remotely, use the weight guidelines below as a starting point and call us if you're unsure.
Soft
Soft mattresses allow more sinkage, particularly at the shoulders and hips. They work best for side sleepers and lighter-weight people (under 130 lbs) whose body doesn't generate enough pressure to sink into a medium or firm mattress. If you sleep on your side and wake up with shoulder or hip pain on a medium mattress, the problem is usually lack of pressure relief — a softer surface lets those joints sink to a neutral spine position. The risk with soft mattresses is that heavier people bottom out into the coils or bottom layer, which creates its own alignment problem. In our futon lineup, soft fills are cotton or foam construction; they break in quickly and feel noticeably different after the first 30 nights.
Medium
Medium is the lowest-risk firmness choice for first-time buyers and for households where more than one person sleeps on the mattress with different preferences. It provides enough support for back sleepers and enough give for side sleepers in the 130–220 lb range. If you're ordering without testing, medium is the default recommendation. Most of our mattresses ship as medium unless specified otherwise, and medium is what we put on floor frames that aren't specifically labeled soft or firm. One thing to know: hybrid mattresses (cotton batting over coils) feel firmer as a sofa than they do as a bed — the coil layer compresses differently under sitting pressure than under full-body lying pressure.
Firm
Firm mattresses resist sinkage and work best for stomach sleepers and back sleepers with lower back pain who need a flat, supportive surface. Heavier sleepers (over 220 lbs) also tend to prefer firm because they apply enough pressure to compress a medium mattress past its intended feel. In our cotton-fill lineup, firm mattresses feel noticeably harder the first few weeks before the batting breaks in — if you order a firm cotton mattress and it feels like sleeping on a board for the first two weeks, that's expected and it will soften measurably by week four. If it's still uncomfortable at six weeks, call us.
The futon-specific wrinkle: sitting vs sleeping firmness
A futon mattress that reads as 'medium' when lying on it will feel noticeably firmer when sitting on it — sitting applies concentrated pressure through the thighs rather than distributed weight across the whole surface. This surprises people who test a futon in the showroom lying down and find it comfortable, then feel like it's too hard once they're using it as a sofa daily. The reverse also happens: a firm futon that feels uncomfortable for sleeping can feel perfectly supportive as a sofa. If your futon is primarily a sofa with occasional sleeping, bias firm. If it's primarily a bed, bias soft or medium and accept slightly less sitting support.
