      When I first saw this foundation I was turned off because I had (another) thing to put together. Just moving into a new apartment, everything has to be put together. I didn't expect this to. I went ahead and bought it and to my surprise after taking it out of the box, it was so simple and easy to put together, "even a caveman could do it". Not much effort at all. It took me, oh, about an hour and that was because I was eating breakfast in between and enjoying music. By the way, it is very sturdy and looks great with the cover. I would recommend this over and over!!

      I didn't read the reviews so freaked out a little when I opened the box. But I put on my handywoman pants and got to it. I assembled it on top of the frame just because I didn't want to lift it later. This was a swell idea. The assembly wasn't hard and it went fast. I look forward to NOT sleeping on the floor! Yay!!! Overall pretty good item for the price.

      Amazing how easy this 4" PostureLoft low profile Foundation was to assemble! If you don't have a large area to assemble this (mine is queen size), I placed two heavy blankets on both running boards of my bed and then assembled the foundation. Looks are deceiving! After removing the frame from the shipping case the wood is so light and yet; extremely sturdy. Assembling this was under 20 minutes. Have a power screwdriver at the ready. The fabric cover is a nice addition and protects any wood on your bed's side boards, foot and head boards! Great purchase for a heavy gel memory foam 14" queen size bed.

      I purchased a Scandinavian platform bed and didn't want the tall box spring on it w the mattress so I put just the top mattress on which was fine but just a little painful hitting my knuckles when I made the bed. I got this low profile box spring and it raises it just the right height so the top mattress is up from the frame but not too high that I need a skirt or anything to cover the low profile mattress. There was more assembly than I anticipated but it was easy.

      We bought a platform queen bed for our guest room; however, when we added the mattress, it was too low. We ordered this and the extra 4 inches were just what we needed. Easy to assemble, and great price too.

      I wasn't sure about this after reading all the other reviews but the positive outweighed the negative comments and I went for it. So glad I did! It is perfect. Two of us worked together, followed the directions and it is one solid, well-built foundation for the queen size gel latex mattress that I had ordered from Overstock on Cyber Monday. After we assembled the outer frame, I was afraid the slats would have to be shortened but by using a putty knife to slide the end into the grooves, it worked absolutely perfectly. Strong, sturdy base and the cover slid right over the top, mattress went on over that and I get zero squeaks, perfect support and would buy again in a heartbeat. My friend who helped me has decided to buy the same mattress/foundation I bought because he was so impressed with the quality. If you use a regular screwdriver to start the screws, we had no splitting, no problems and a very good experience!

      I Have to purchase a foundation for our new bed and mattress. California King mattress do not have box springs. Kinda miss the spring action but is still very pleased with the new foundation. It uplifts the mattress so that it doesn't sit low. Very easy to put together. Would suggest this foundation to friends.

      This was very easy to put together and worked perfect for a platform bed with 11 inch Comfort dreams memory foam mattress. The total of 2 is now 15 inches and now a perfect height for our new guest poster bed.

      came together nicely and seems to be sturdy. Also nice that it can be taken apart for narrow doors. UPDATE: Have discovered a big negative- this box spring creaks and groans like nobody's business! Whenever my husband or I get up in the night it immediately wakes the other person! So bummed. ANOTHER UPDATE: DONT BUY THIS BOX SPRING! My husband literally ended up sawing it into pieces and burning the wood in our back yard. LOL. So sad we wasted the money... It creaked SO LOUD with every little move. Constantly woke each other up just getting in and out of bed or even rolling over. THE WORST.

      This is a great low profile foundation, if you do not mind putting some work into the assembly of it. The directions were easy to follow it was just missing the screws, a simple walk down to the hardware store I was able to purchase what i needed for *** and get it assembled and into place in about an hour.

    • Total crap
      Verified Purchase
      Option: Queen

      First the shipping carton fell apart. When I brought the box inside the contents blew out the end of the box. I received all the pieces but have no way of returning the item. This listing gives measurements that I specifically looked for and sadly the actual measurements are WRONG. The actual frame is a full 3/4 inch too narrow and too short. My mattress hangs over the edge on the sides and head/foot of the mattress. And it doesn't span the distance of my bed rails. So, I'm now stuck. A very heavy product that is not as advertised, no shipping container, and an item that will likely cost me as much to sent it back as it weighs. One other thing. The picture shows a cover that is white and mine is royal blue! I wanted the white edge so it matched my mattress. I'm very disappointed and frustrated that the information posted was so completely inaccurate. So, what I have is very expensive firewood and fabric that will just be thrown away.

      Installation takes time and electric tools. If using hand tools, expect to be at it a while. Cover is adequate but could be better.

      I can’t believe I ignored the bad reviews - please do not ignore, they are soooo right. Not only do you have to assemble everything, it is very cheap and overly heavy. I had thought it would be like the metal box board but I was so wrong. So disappointed.

      Very easy to assemble. I manually screwed the screws in and then went back and tightened them with a power drill, in retrospect I should’ve just assembled it with the power drill and been done quicker. Slightly heavy to move by yourself since it is wood but doable

      This foundation was very easy to put together and took about 10 minutes to complete with 2 people. It came with a screw tightening tool, but you will need to have access to a Phillips head screwdriver. This will be useful to make my new foundation bed more stable for the mattress.

      Have an Answer? Be the first to answer this question!
    • Q:

      "What is the distance between the slats? I'm looking for something where the slats are 3 inches apart or less. Apparently whoever tried to answer this question the last time I asked has no freaking clue what I'm asking."

      • A:

        This is a typical mattress foundation that is made to sit on a frame with three boards under it on a bed frame. It has 11 slats between the length of 80 inches which is the length of a foundation and/or queen mattress. That puts the slats at over 7 inches. What you could look at is the Europa which is a platform that has slats that are 2.7 inches apart from one another.

    • Q:

      "I need a mattress platform that will fit inside my current bedframe, as it has drawers that slide into the footboard. I have a Purple mattress, Queen Sized, from *. It specifies for the mattress that it must be on a frame where the wooden slats are no further than 3 inches apart. So, on the queen sized foundation, how far apart are the slats?"

      • A:

        The queen foundation is a boxed unit that will hold any mattress with full support and can be a 4-inch low profile or standard 8-inch foundation.

      • A:

        This did not answer my question. How far apart are the slats?

    • Q:

      "Sorry I'm not confident with those sizes....please somebody could tell me what a need if my mattress is 180x200? Thanks, Frederic"

      • A:

        Because the CA King is 72"W x 84"L. That being the largest base. And, are you using this on a regular bed? If so, what size is that bed? Go by the size of the bed to determine the size of the foundation. My bed is a queen. Therefore, I went with the queen size foundation for my coolgel memory foam mattress which is queen size. The foundation is basically a "box spring" if you will. Hope this is helpful. No noise from the bed. Very solid yet, extremely comfortable.
