Rated 5 out of 5 by from Excellent service, excellent product! My wife and I stopped in the store just to check on what’s available, we’ve been putting off getting a new mattress for the past year or so. The salesman, Dan was extremely delightful. Made us feel at home and welcomed to try out the mattresses to decide our best fit between Soft, medium and firm... once you lay in the bed, the mattress chooses you. King size, firm, Serta and couldn’t be happier. Pricey but worth it when it comes to sleeping and comfort for the next 10+ years. Great purchase, great product, great service.

Rated 5 out of 5 by from Super Phenomenal Service!! Rose from Oceanside, New York Mattress Firm was very professional and very honest and upfront with all answers to my questions about my new mattress. She also gave me the option of picking out a very comfortable pillow; even gave me option of trying out 3 different pillows and provided a clean cloth to place over each pillow while deciding the one most comfortable to me::::!!!!!! Awesome saleslady! By the way I love my new bed too! Great for my sore back!!

Rated 3 out of 5 by from Very responsive i placed an order for 2 bunky boards by phone with my local store, and the person on the phone was great. helpful, responsive, informative, and transparent. I elected to purchase the boards on clearance, which i understood were previously sold and returned, and then thoroughly sanitized for resale at a much lower price. They were delivered in less than 24 hours by 2 very pleasant, helpful delivery men. HOWEVER, the boards were stained and the cover on one was ripped. since they were polybagged, i am assuming that the problem occurred in the resanitizing. But since i really needed them (my husband would be home that day after 3 weeks in the hospital) and i believed the service person on the phone, i decided to just keep them. I would never buy on clearance again, but i would consider doing business with Mattress Firm again.

Rated 3 out of 5 by from bad sales associate The sales associate Lynn was not very accommodating. She was very indifferent about her job. Would not recommend this store. I ordered the mattress on 1/14/18 and filled out the forms for the Fibit, but have yet to receive it. If you advertise something you should deliver on it. I have no way of following up on it. Also, the bed frame is cheap and noisy for a mattress costing $1,500.00.

Rated 5 out of 5 by from You get what you pay for!! I ordered a mattress online that came in a box. What was I thinking? It was too soft for me even though I got their firm mattress. I went back to what I know...Mattress Firm. I was able to lie on all of the mattresses in the store until I found the right one. My mattress was delivered the next day and I’ve been sleeping soundly ever since. You get what you pay for!!

Rated 4 out of 5 by from Great Went in for a purpose and got what I needed. The store offers different price point selections but of course the best, more expensive options are laid out ready to be tested. Overall, the delivery was at my convenience, and the product is pretty good. I'll be paying it off for a while but I do love the 10 year warranty. I went here because it was close to home.

Rated 5 out of 5 by from GREAT SERVICE I was so happy that my girlfriend and I purchased our king size mattress from Mattress Firm Oceanside South. Greg Ryan was the salesperson who helped us and he was amazing. He was knowledgeable, honest and just a great person to deal with. I would recommend this store, Mattress Firm Oceanside South to anyone who is looking for a mattress. Ask for Greg.
