Rated 5 out of 5 by from Awesome expierence! I had been looking for the right mattress for sometime now. I walked in to Sleep Train for the first time and was greeted by the manager, Sannya. She didn't try to sell me on the most expensive bed. She first took the time to figure out what type of mattress was best for me and my comfort. I told her I couldn't spend a crazy amount of money. She totally understood being a mother herself. She took great care and time with me. Never rushed me. She gave me all the discounts and coupons she could think of. Never treated me like a number. I would for sure recommend Sleep Train in El Cajon. Best mattress buying expierence ever!

Rated 5 out of 5 by from Would do it again. Buying a mattress is kind of a "grudge buy", you need 1 but you don't want to spend a lot of time or money on it. Went into the store, John greeted us and found out what we wanted. Found out we had just come from another store, looked up that store's price on the mattress. Found comparable mattress for us, beat their delivery by 5 days, price by 5% and got us outta there in less than 30 minutes. Nice work. He told me the delivery guys would call in 2 hours to book window to deliver later that day. As I am typing this review I am approaching the time to get our new mattress and have the old one hauled away. I am on " the train" and will definitely recommend to family and friends.

Rated 5 out of 5 by from great customer service & knowledge I called Sleep Train the night before we went in. I was in a hurry to buy a good quality mattress for my son. I spoke with John Loomis and asked him several questions and he was so kind and helpful. The following night I went in with my son and was thrilled to see John was working. He remembered me from our phone conversation. He was so helpful and educated on every aspect of our inquiries. He truly helped us find the perfect mattress, pillow and cover for our mattress. Thanks John, for caring so much about your job, and Sleep Train for having such a nice selection of mattresses and speedy delivery.

Rated 5 out of 5 by from Love this Sleep Train location Donna is an amazing sales person. She took a lot of time to make sure we were comfortable with our purchase and getting the best mattress and price for our needs. She was honest, helpful, and knew everything about each of her products. I would highly recommend this Sleep Train location over all the rest. The return/exchange policy is of the utmost importance to me. It gives peace of mind knowing you're not stuck if you don't get the right one the first time around. I've learned the hard way by shopping at another store, but came right back to Sleep Train a few months later.

Rated 5 out of 5 by from Very knowledgable My husband and I are newlyweds and embarked on our first mattress journey this past weekend since my previous mattress was too soft for him. The sales associate, John, was not only attentive, but very knowledgeable. After hearing how we each sleep, he systematically pointed out mattresses he felt would accommodate both our sleeping habits and budget. It was a much better experience than we had at the big furniture stores and we confidently bought our mattress within thirty minutes of entering the store.

Rated 4 out of 5 by from Great mattress Its been a few weeks since buying and I have been sleeping so good. It's amazing what a good mattress can do for you. I had a small issue with the sales person as I had told her that I wanted a firm mattress when we met but she kept showing me plush mattresses because I had said that I slept on my side. I didn't realize she was showing me the wrong ones and I was wondering the whole time why they were all so soft. I finally saw what she was doing and ended up buying the firm mattress I was looking for.

Rated 5 out of 5 by from SUPER HAPPY WITH OUR MATTRESS BUYING EXPERIENCE My wife and I recently went in to purchase a mattress and were assisted by Janet. She not only helped us find the right mattress, but adjustable base, mattress pad, sheets and pillows. It was one of the best sales experiences we've had, she went above and beyond, even after the delivery of our mattress. We will not buy a mattress from anyone else, if you are in the market for a mattress, go to the store on 790 N Johnson Ave., across from Parkway Plaza, and ask for Janet.

Rated 1 out of 5 by from You buy more than a product, you buy the service. I purchased two beds and they are wonderful however the service was horrible. The sales man promised things the drivers don't do and when asked the salesman changed his story. The delivery drivers broke a light, didn't wear covers on their shoes and argued with me the entire time. They also left the work half done for the next day. I will NEVER purchase with this company nor will I suggest anyone use them. I was also over charged and did not receive what I paid for.
