Say you’re a petite 5 feet tall, and your partner is a robust 6 feet 2 inches. You sleep on your side, and your partner is a back sleeper. Now, thanks to our newly expanded mattress ratings, you can drill down past the overall score and zero in on only those mattresses that suit you both. The key to comfort in a mattress is support. A mattress for people who sleep on their sides should keep the alignment of the spine fairly parallel to the bed. For back sleepers, we measure how well it maintains the natural curvature of the spine in that position. But, as you may already know from painful years of experience, the same mattress doesn’t necessarily offer the same level of support for people of different statures. So we use test subjects that represent the lower and upper 5 percent of the population by size. Our petite women range from 4 ft 11 1/2" to 5 ft 1 1/2" and 110 to 127.5 pounds, and our large men range from 6 ft 2" to 6 ft 4" and 220 to 242 pounds. For each of them, we measure support while on their sides and on their backs, then average those scores to get the result for a midsized person.
That’s how we came up with six columns for support: petite, medium, and large/tall side sleepers; and petite, medium, and large/tall back sleepers. The petite side sleeper will find only one mattress that scores excellent for his or her stature, the Sealy Posturepedic Hybrid Trust Cushion, a $1,275 innerspring. For all the other body sizes, it scores very good but not excellent. If you prioritize the large/tall back sleeper’s comfort, the Charles P. Rogers Powercore Estate 5000 has excellent back support and very good side support. It scores one point higher overall and costs $1,500. (Online subscribers can sort the ratings by columns, making this exercise even easier.) Support isn’t the only factor for couples. A healthy person shifts positions 40 to 60 times per night. Double that for a couple, and that’s a lot of tossing and turning for any mattress to cope with. That’s why we also test for stabilization, which is essentially a gauge of bounciness. It provides a very good indicator of whether your movements will disturb your partner, or vice versa.
Only four of our 74 rated mattresses aced the stabilization test. Of those, the highest-rated overall is the Sleep Number c2, $800, one of two adjustable air mattresses we tested. The other three stability stalwarts are innerspring models, the best of which is the Sealy Posturepedic Hybrid Elite Kelburn, $1,350. None of the memory foam mattresses earned excellent scores for stabilization, so steer clear of that type if this is a big concern for you and your partner. That said, plenty of foam mattresses have very good stability, so it becomes a matter of priorities. And while you may have to make a few compromises when shopping for a mattress for you and your partner, we hope our new ratings will bring you that much closer to somnolent bliss.When you are expecting a new baby, shopping for a crib and mattress can be very exciting. But it can also be stressful, once you become aware of the problems surrounding conventional mattress production. Many contain toxic materials such as fire retardants, plasticizers, polyurethane foam, and vinyl (PVC) that have been linked to problems with child development.
There is also a theory that SIDS is caused by the toxic chemicals released by conventional crib mattresses. When a normally harmless household fungus (Scopulariopsis brevicaulis) comes into contact with the elements of phosphorous, arsenic, or antimony that have been found in chemical fire retardants in mattresses, it can generate extremely poisonous gases that are far more toxic than carbon monoxide. (Read more about it here.)New Zealand has been wrapping many of its conventional crib mattresses to seal in the toxic chemicals since 1995 and has noticed a 72 percent reduction in SIDS. The campaign, spearheaded by Dr. T.J. Sprott, has seen nearly 205,000 babies sleeping on wrapped mattresses with no deaths, while crib deaths on unwrapped mattresses were reported to be 975 in the same time period.So it’s definitely a worthwhile investment to buy a ‘clean’ crib mattress for your new baby. If that’s too expensive, then consider purchasing a BabySafe Mattress Cover, which is the non-toxic plastic ‘bag’ used by Dr. Sprott.As a follow-up to my recent post about VOCs emitted from foam crib mattresses, here is a list of alternative green mattresses for your baby:Perfect for really young babies, this mattress is handmade using organic cotton and premium wool batting.
