i just bought Slumberland queensize mattress Tempsmart II 1600.. **** shiok, i lie down already almost fall asleep at the courts showroom. paid 2899 plus bedframe and 2 free microgel pillow. before buying i tried the norm - simmons, sealy, serta but none of them is as shiok as the tempsmart i bought.. even the other slumberland mattresses "hotel range" kind also not as shiok.. the tempsmart technology is supposed to keep u cool at night with ventilation blah etc.. but really shiok lar i highly recommend everyone to go and try
