Lifetime Outdoor Sheds are perfect for a variety of uses. They are built to the highest standards and have a very attractive look for just about any yard. The frame is steel reinforced and the walls, floor, and roof are made from polyethylene plastic, which will not fade, crack, or peel when exposed to sunlight making these sheds a better option than other vinyl sheds. Sky lights allow for natural light to permeate down into the shed.

Nice shed , must be on flat ground. Ours is on the patio with a shim under the door and we have to put a tapered board under it to level the floor. The floor goes together first and make sure the holes for the doors are in the right place or you'll be rigging some holes which is what we had to do even though we followed the instructions , some how floor did not end up quite right. Sturdy shed once put together, hopefully the material its made out of will handle tree branches that fall, not quite sure but time will tell and we have a few 100 foot Oak Trees. It took two full days to put together.

5 out of 5 stars Easy Shed,Headroom!!!
by Hubb from Long Island, NY on 9/5/2013
Recommends it to Friends: Yes
After searching the local Home Depot and Lowes as well as some other local shed places found this to be the best value. Free Shipping No Sales Tax. Saved $300 from buying at Lowes or HD. Relatively easy assembly very sturdy and roomy inside. Good headroom, no more ducking while in the shed. I am over 6 ft tall and it is much more comfortable to bring things in and out of the double doors without whacking my head on the door frame. Truss system easy to assemble and while you do need two people only one needs to do the assembly. The other person basically is there to hold panels while you screw them together. Good father son project LOL

5 out of 5 stars Incredible Deal - Incredible Shed
by T. Nadritch from Rochester, NY on 8/15/2013
Recommends it to Friends: Yes
First of all my dealings with Competitive Edge have been nothing short of amazing, from the initial call to the follow up on delivery they have been incredibly friendly and helpful. The shed arrived roughly a week after purchase as expected and although the directions can be a little difficult to follow, it was easy to build. The hardest part of getting the shed up is building the base for it. The base took about 1/2 a day to clear and level then the shed went up the following day with the help of a few friends. Be prepared to work on it for a full day to ensure that it goes up properly. After it went up, I couldn't be happier with the shed!

Love everything about this shed. It was delivered within 8 days. They put it as close to the location as they could get. Was easy assembled with a couple guys and looks amazing. We extended a deck area big enough to put the shed on. Great size. And we are very pleased with this product. Plus free shipping!!!

4 out of 5 stars Great Shed
by Packer Backer from Green Bay Wis. on 7/31/2013
Recommends it to Friends: Yes
Received 8x15 shed at 11:00 am. With the help of one to two people had the shed put together on cement base at 8:30 p.m. After 9 hours of careful reading of insulation instructions the shed looks great in our back yard. The neighbors kept telling me how good the shed was looking as we were putting it together. This shed makes the whole back yard look better. The instructions could have been a little better written but we finally were able to follow them.

2 sometimes 3 of my neighbors came to help me put up my new shed. Its instructions were very easy to follow and the shed went up in 1 day. I would recommend this shed to anyone. The hardest part was cutting my lawn out, (hired a young man), and leveling a stone dust base. I had to level, pack, water, re-level several times to get the level that I desired. I do wish that they had a roll up door option for the end as I am working on constructing my own. RC Newburyport, MA

5 out of 5 stars VERY well designed!
by SacTownWalt from Lifetime Reviews on 5/26/2014
Recommends it to Friends: Yes
Wow, I’m impressed - very well designed and the instructions were great (a major improvement based on previous reviews). Assembled the complete shed by myself in a weekend. I’d built a pier & beam foundation in advance – two 8’x8’ sections, bolted together because I couldn’t haul 16’ lumber. Reasonably level, but not perfect. The pallet arrived Friday afternoon – the big 8x15 unit with 2 sets of doors. I hauled the 2 smaller boxes into the backyard as-is. I split up the 2 larger boxes, unpacking half the contents into the box top and hauling the half-full tops and bottoms separately. Spent a couple of hours Friday evening assembling the roof trusses and watching the how-to videos (They're very clear, helpful, and worth your time !). Sat AM I assembled the doors, one of the few areas where more detailed info would’ve helped. I made a few mistakes that took some time to undo and correct. (Tip –a little lithium grease helps slide those long metal edges over the door panels.) Once the floor was down the wind kicked up, knocking down walls fast as I got ‘em up until I used a pair of ladders (one inside, one outside) to hold ‘em in place. Then install those ¼ circle shelves to brace the corners and the long shelf to brace the sides (a bit premature per the instruction sequence, but it worked for me). The ‘dueling ladders’ came in handy for the roof too - one inside and one outside. By end of day Saturday I had all the walls up, with the end doors installed, and roof panels on both ends. Sunday I installed the 2nd set of doors and the center roof sections with the dormer. Everything fit pretty well, although I did make liberal use of the rubber mallet. The doors hang straight and close easily. One set has a ½ inch vertical offset, but not enough to cause any problems and I didn’t want to risk other issues by shimming the floor. Let it sit for a week, then this past weekend I built a redwood step for the end doorway, and a wide ramp for the long side. Got some new shelving units inside waiting for assembly, and I’ll add some battery or solar lights as well as a ‘semi-permanent’ AC extension cord hookup. Now I’ve got plenty of room for the toys, tools, and gardening supplies too. Definitely a worthwhile investment!
