I did an incredible amount of research on mattresses as well as visited several mattress stores before purchasing from Great Offer Stock. I was looking to upgrade to a reasonably priced, firm king mattress that had a minimum of motion transfer as I am a light sleeper. Everything I wanted is in the Beautyrest Recharge Maddyn as it has both memory foam and wrapped coils. I am experiencing longer, deeper sleep with this mattress and it is very, very comfortable. White glove delivery was an added bonus to this purchase. Delivery persons were prompt, courteous, accommodating and professional. My bed arrived about 8 days after I ordered - delightful surprise. I had narrowed my vendor choice to two companies but IKEA customer service, even with live people, just doesn't compare to the help Great Offer Stock people provided me. Thank you, Great Offer Stock, for a great purchasing experience.
