Rated 3 out of 5 by from Service The store and staff that we purchase the mattress was good, very aware of products. Prior to this store we went to another Sleep Train Store in San Marcus, the sales assoc. was very pushy, we were undecided, I asked if were came back on Thursday, could we get the same offer on the $300 sheet offer, he said "No", I felt he wanted us to buy the mattress then. When we said we were undecided, he quickly went to another customer & said to them, "now I can give you my full attention", then we left. Days later we went to the store that we purchased the mattress & received the same offer, very nice sales assoc., not pushy, very helpful.

Rated 5 out of 5 by from Superb service We walked into Sleep Train two successive nights and received the undivided attention of two different sales persons who were very knowledgeable about Sleep Train products. Were were not rushed and both sales reps answered all our questions to our satisfaction. It was a very pleasant experience, and we placed an order on the first night followed by an adjustment to the original order since Sleep Train not only meets any competitors price, but gives a 10% discount on top of the on-line competitors price - no questions asked. Of course to get the price reduction one needs to bring proof of the advertised price on the same item.

Rated 3 out of 5 by from King size bed frame ... I bought a kinda size bed and was asked if I would like a standard bed frame or "heavy-duty". I opted for standard thinking the standard would work fine if it's an option. We got the mattress set up and when you sit on the end of the bed, the whole bed tips forward! I called back to sleepytrain and the sales rep said "well yeah, you got the standard frame which is not long enough for your mattress type, you need a heavy duty frame." Wait whatttttt why wouldn't you tell me that BEFORE?! Anyway.... returning the standard to get the heavy duty on Monday. Note to public- get heavy duty frame when buying a king sized bed!!

Rated 3 out of 5 by from Exchanged our mattress We bought a queen mattress and felt that we were both dipping into each other as we slept still (after we gave up our 10 year old mattress that had the same problem) so we decided to go back and upgrade to a king. The sales man spoke very fast and was very hyper but it was a fine experience. They exchanged it with no problem. But when the delivery came, there was a huge stain on the underside and it was sticky (directly on the mattress) so I called the sales guy and he said he would take care of it. They are supposed to come next week to swap out for a clean one. I just wish that we didn't have to go through the hassle of swapping out 3 beds 3 times but it is what it is.

Rated 5 out of 5 by from Terrific Experience I checked Consumer Reports and knew the mattress I wanted. I called the San Marcos store and was told they could get the mattress for me and that the Escondido store had one on the floor as a demo. Before I could drive to Escondido, the Shawntee at the San Marcos store called back to say a demo of the mattress I wanted had just been delivered. When I went into the San Marcos store, Shawntee, who I had spoken to earlier was not in. The manager, Clair, helped me. She was fast, friendly and knowledgeable about the mattress. She made helpful suggestions, rang up my purchase and had me on my way in no time.

Rated 5 out of 5 by from Best Service EVER I am more then happy to tell everyone that will hear me that I had the most wonderful service at this location on Grand Avenue in San Marcos. Liam Scott was not only knowledge about the products he was very honest...I like that in a person. I hope it is okay to mention his name here...he is a great salesman with a pleasant attitude. I want him to be MY salesman every time I buy something! He was easy to understand and took his good time for me. All my questions were answered and I left there with a amazing bed that I call the "CLOUD"~~~Sleep Train should more young men like Liam!! Also the manager there was right on! I had a size issue and she was spot on with the problem! Thank you Clair!

Rated 1 out of 5 by from Poor experience I purchased my bed there and it took 3 times to get my delivery correct. When we finally did get it delivered the delivery people were very rude and offered no assistance. The manager on the phone was of no help at all either. The store gave me incorrect information about my bedroom furniture that I already had. The drivers were in a huge hurry and wanted to get out as quickly as possible. No one had me inspect the furniture once it was assembled they just walked out the door. I was very displeased with my buying experience.

Rated 5 out of 5 by from Good quick service I am always a little apprehensive when I go into a sales room that I will be bumbarted with salesman looking to continuosly up sell, so I tried to do my research online, but you do need to lay on the beds to know what you like. Dillon did a nice job making me feel comfortable and guided me to which bed I might like best based on how I sleep. He even showed me other options that were a bit less in price. I ended up going with the bueatyrest plush 1000, which is what I went into the store thinking I would get but he made it easy. The only thing is he probably could have let me lay on it a little longer before asking me about it. His help with financing options and getting me out the door knowing I made a great purchase was invaluable.
