hi AK, we had intended to buy Sealy mattress after hubby slept in a fantastic one in an hotel overseas.... but when he came back and we did our research, found out some things.
Sealy mattress is posturepedic...meaning it helps support and give good posture....the technology it uses helps the shape and mould your body when you sleep, but as its intend is posturepedic, it doesn't support your lower back as much.
For SImmons, it is orthopedic, and its beneficial to your back. its molds your lower back, giving it the necessary support when you sleep.....it protects your back...the technology is same either for backcare or beautyrest series, though backcare is generally firmer...
when we tried on both sealy and simmons, we also noticed that due to the diff in tech mentioned above, sealy mattress does not give as much undisturbed sleep as simmons. when u turn around on sealy mattresses, the other party can feel it. and sealy mattress are more bouncy....when u try bouncing on both u will know. simmons give really good support, and ensure the other party sleeps undisturbed.....esp for the mid range kinds onwards, e.g. the canterbury, westbury, felicity and such...
as for pregnant ladies....hmmm.....one of the most strainous thing abt being pregnant is supporting the foetus and putting strain on your lower back....so i personally wld think from this argument simmons is more suitable....if i am not wrong, the comments u heard above shld be from a sealy sales person issit? hehhehe...
anyway, just my two cents worth....ciao...btw, ours is a westbury...
