The introduction of the Durable Blow Molded Lifetime Outdoor Storage Shed 8 x 10 has rocked the outdoor storage industry, proving once again that innovation, passion and a drive to make better products can revolutionize an entire market.

Do I need to build a platform or base or pour a pad for shed 6405?

Before beginning the assembly of your shed, you must pour or construct a platform. There are four types: concrete, wood frame, road base-filled wood frame, and pea gravel wood-filled frame. The actual dimensions of your shed, at its widest and longest lines are 96 inches by 120 inches. Ensure you select a site that will accommodate these measurements. The floor dimensions are slightly smaller than this; therefore, you will need to create a level surface that is 93 ½ inches by 118 ¼ inches. The instruction Manual show you exactly how to construct it and what materials are needed.

5 out of 5 stars No Better Deal Around
by BadBoy from DFW, TX on 1/18/2014
Recommends it to Friends: Yes
Starting off, Competitive Edge has THE best prices to be found. Second, Free and Fast Shipping directly to your door. This shed is a solidly made product made with precision. If you have/had any problems putting it together it is because you did not have a flat level base. You should spend ample time working on whatever type of base you are constructing to make sure it is flat and level. If you do this the construction will go very smoothly. Instructions were clear, laid out well, and easy to follow. I put the entire shed together by myself in about 6 hours including a break for lunch. I did have my daughter (13) assist with holding the skylight pieces in place while I screwed them in place. I highly recommend this shed! High quality craftsmanship that should last longer than the 10 year warranty.

4 out of 5 stars 8 x 10 Shed #6405
by Picasso from Capistrano Beach, CA on 4/24/2013
Recommends it to Friends: Yes
Received my shed and everything is good. I would have liked the longer shelf to be wider but, over all I love it. Maybe for the future of Lifetime Sheds, you can display how some sheds are being used with photos on your website. Maybe have a contest for the best use of your product/decorated and put the photos on your website. Customers can send in photos of their shed decorated and can win money or a gift card or free accessories for their shed. I am not using the shed as your typical shed but for an artist studio! Thank you! Annemarie Ross

4 out of 5 stars Needs better instructions
by retired from Sierra foothills on 8/24/2012
Recommends it to Friends: Yes
We really like the shed and figured out how to put it together but we feel the instructions are very inadequate. Would be great to have an instruction DVD included along with a more detailed written instructions manual rather than just the pictures. I see after having put it together also that there is a parts list online but it would be nice if there was one shipped with the shed.

Recommends it to Friends: Yes
the shed is very nice, however, the directions were in pictures only. there should have been the written word along with the pictures. it would have made it much easier to understand. when i looked at the instructions on line , it was stated in words as to what to do--- which made it much clearer.

5 out of 5 stars installation was a "snap"
by customer from Deltona, Fl on 12/27/2011
Recommends it to Friends: Yes
First, I want to say how professional the service has been with Competitive Edge Products. From the order to the delivery, attention to detail has been outstanding. Second, the item purchased Lifetime 6405 8 x 10 storage shed was exactly as advertised. The installation was a "snap" no pun intended. Third, I would recommend your company to anyone interested in a similar product or any other product offered.

5 out of 5 stars Attractive, well built, easy to assemble
by bjm from Redding, ca on 11/29/2011
Recommends it to Friends: Yes
We really like the shed. We spent about 6 weeks researching different types of sheds, wood, metal and vinyl. We landed on vinyl because of cost and no maintenance. We then looked at various manufacturers of these sheds and landed on this one. The sturdy construction with steel reinforcing is what sold us. We have extreme temperatures here and having the extra support was important to us. The instructions were very well written and easy to understand. I especially appreciated the instructions for various types of foundation that could be made for the shed. I was having trouble finding what we could do on our property and ended up with a very simple design that was one of the ones proposed in the instructions. I was able to do most of the shed by myself but the walls are easier with help. Follow the instructions carefully and it goes together really well. The only part of the instructions I felt could be better are the ones showing the dead bolts. I figured it out eventually, but more detail would be good on the instructions. I have showed pictures of our final product to friends and they have all asked if it was a picture form an advertisement. I would also say I was really impressed with Competitive Edge. They not only had a very competitive price, but we ordered it on a Saturday and it arrived on Tuesday. We are very happy with this shed and have already recommended it to a couple friends here in town.
