World Class Resonance 14.5" Plush Mattress is rated 4.0 out of 5 by 69.
Rated 4 out of 5 by from Great service from Kimberly I received excellent and knowledgeable service from Kimberly in the Hodgkins location. She was very informative and patient and I felt that she truly cared about the right decision for me. I would recommend her services to anyone. The delivery men were also very good and careful not to do damage to my house as they maneuvered a queen-sized mattress and box spring into the upstairs bedroom. Unfortunately, the company was going to through a transitional process at that time of my purchase and I did not receive delivery until many days later, which was inconvenient. However, I believe this was temporary and that delivery service is back to normal.

Rated 3 out of 5 by from Started off great Comfortable but when delivery guys left I found holes and tears in the mattress and box spring... For the amount I payed I expected better quality. Now I'm disappointed that I didn't shop around. Great customer service though.

Rated 2 out of 5 by from Comfortable but HOT! The first Simmons Resonance mattress we received was hard as a rock and developed large dips within the first 60 days. So large that you could see the dips even when the bed was made with a comforter. We went back to the store and they agreed to exchange for the same model. The salesman said it wouldn't be unusual to see Simmons put the wrong interspring in the mattress and that could be the reason why it felt so different than the one in the store. As far as the dips, he said it sounded defective. He was correct - the second mattress (same model) was completely different, soft and comfortable like the one in the store, but his one is EXTREMELY hot. The mattress stays warm even after you get out of bed. We've had the mattress for less than a week but will need to return as neither my husband nor I can sleep on this hotbox.

Rated 5 out of 5 by from In sleep heaven with this mattress! My favorite feature of this mattress is everything. The material that surrounds the edges prevents you from sliding off. The 1000 coils are supportive and so comfortable for back, side or tummy sleepers. The 14.5 inch height is great for a luxurious, high-profile look. Mattress-Firm also sells a lavender infused memory foam pillow that is an extra treat!

Rated 5 out of 5 by from Davy's Hunter, Salesman I recently had the pleasure to interact with Davyn Hunter, Salesman at the North Palm Beach MattressFirm store. He was extremely knowledgeable of all the products in the store and was extremely patient with me as I narrowed down the right mattress, box spring, frame and mattress cover to meet my needs. He also worked with me to give the be best deal possible. I highly recommend this store location and Davyn to help you through the decision process.

When you recommend rotating are you suggesting to flip the mattress or change the head to the foot?

Asked by: Bethm
This mattress cannot be flipped. We do however, recommend rotating from head to toe for even weight distribution over time. This will help prevent unnecessary wear and tear.
