I purchased an Englander 575596LT Sienna Latex Pt mattress and box 6/6 and was delivered to my home on [protected]. On 11-13-2009 the salespeople came at a charge of $53.17 to check my complaints of sags, lumps, soft spot and noise. They fluffed the mattress, pulled the pillow top and measured. The box was broken and replaced. Now 3 months or so later I am have the same problem with the noise, but the sags, lumps, soft spot never went away. If I call the salespeople out again I will be charged $53.17 to tell me I have a broken box. I feel that this mattress set is defective and it should be checked from a representative of the company. I purchased an Englander mattress set in 1999 and it is the best mattress I have ever owned. Something is not right with this mattress set.
