It sagged in less than 3 months

The LOTUS STYLE Queen size MATTRESS and MATCHING BOX SPRING as well as a NEW METAL BED FRAME STARTED out GOOD, but NOT FOR LONG!!! I have several bodily injuries from the past from my neck, back, shoulders, knees, hands, ankle and feet. I got the LOTUS Queen size MATTRESS with matching box spring and was on the moon for the comfort but in LESS THAN 3 MONTHS it SAGGED SEVERAL INCHES. I contacted the retailer, who in turn contacted SYMBOL MATTRESS COMPANY. It FELT like it basically TOOK an ACT of CONGRESS to GET the MATTRESS REPLACED!! I had to take my bed apart layer by layer to SHOW that it had a MATTRESS PROTECTOR ON it AND that I was USING a PROPER BOX SPRING (the one that came with it) AND the TYPE of FRAME I was USING with it. Finally AFTER OVER 6 MONTHS, Symbol replaced it with a DIFFERENT mattress, BUT the LOTUS Queen size style mattress set was NO LONGER AVAILABLE, so for and EXTRA $100.00 on top of the $580.00 I'd ALREADY spent, I purchased the OXFORD STYLE Queen size MATTRESS as well as the MATCHING BOX SPRING. Again, it STARTED out GOOD, BUT.... in LESS THAN 1 YEAR it started showing SIGNS of BLACK MOLD!! I contacted the retailer who in turn contacted Symbol Mattress Company. They WILL NOT REPLACE it because THEY say that it's CAUSED from the ENVIRONMENT!!!???? Explain to me how a mattress set can show BLACK MOLD in LESS THAN A YEAR from the TIME OF my PURCHASE??? The RESEARCH I looked at SUGGESTS that the black mold was PROBABLY ALREADY IN the MATTRESS BEFORE I BOUGHT IT and HAD just now WORKED its WAY TO the SURFACE where it is VISIBLE!! DO NOT EVER BUY A SYMBOL MATTRESS if you don't have money to waste! THIS SYMBOL MATTRESS COMPANY is a JOKE for any type of WARRANTY or REPLACEMENT OF THEIR PRODUCTS!! BEWARE!!!!! I WILL NEVER PURCHASE ANOTHER MATTRESS/SET from the SYMBOL MATTRESS COMPANY!! I am sharing this review of my terrible experiences with you to try and save anyone else from having to go through what I have. Bottom line....DON'T BUY ANY PRODUCTS fro SYMBOL MATTRESS COMPANY!
