The worst purchase ever. We've purchased two king size mattresses, first 6 months ago, second a month ago, and both are having deep ocean waves, ALREADY?!!!!!!! Our previous mattress from IKEA (very cheap, purchased more than 4 years ago) is still fully functional without any deflection (not even a 1/16")... Now, instead of having a good quality sleep, SLEEP COUNTRY gives us nothing else but frustration, back pain, and anger! Whoever is considering Sleep Country for their next purchase, please, save your wallets and get a mattress somewhere else! It's NOT worth it!
