No to sleeper couch at Decofurn

I purchased a sleeper couch from them and within 8 months the springs were visible on the couch. They replaced it with a new couch and with in 1 week I had the same problem. Again they replaced it but this time with a couch that they replaced a broken arm rest and you are not able to store extra pillows and again within a week the couch springs are visible. They now refuse to replace the couch or provide a store voucher.
